Honour your senior master conductors: there aren't so many of them left now. Abbado and Haitink spring most readily to mind, but orchestral musicians may also nominate Neeme Järvi, who celebrated his 74th birthday last week. A passionate patriot and the man his country voted "Estonian of the Century" in 2000, he proudly sports the colours of the national flag in concert attire by virtue of a natty added blue handkerchief.

It’s a quirk of the acting profession that someone can fly under the radar for years and then suddenly be catapulted into the limelight. Nigel Lindsay's impeccable record in contemporary plays at the Donmar, Almeida and Royal Court has left all but keen theatre-goers with only a dim sense of his distinctive profile. He is currently performing his most high-profile role yet - unless you count the doltish white Muslim jihadist Barry in Four Lions. But one thing will not change. To play the grouchy Scottish ogre in Shrek the Musical (in which he's been coached by his old mate David Tennant), Lindsay will spend 90 minutes before every performance having prosthetic make-up applied. When he walks out of the stage door, the junior hordes won’t know him from the doorman.

Seasick Steve Wold (b 1941) has achieved widespread popularity over the last five years with his raw, rootsy, blues-flavoured sounds. He's also renowned for his customised guitars, such as one featured on his new album, You Can't Teach an Old Dog New Tricks, that's made from Morris Minor hubcaps, and for his stage patter which combines US Southern charm with hobo lore and anecdotes.

The identity of British independent film, and its future directions, has always been a matter of some contention – and with the ongoing transfer of authority on funding issues from the now-defunct UK Film Council to the British Film Institute, it’s a question that isn’t going to go away. For Ron Peck, whose most recent film Cross-Channel has been released on DVD, coinciding with the re-release of his Empire State, it's a question close to the heart, as director of what has been called Britain’s first openly gay film, Nighthawks, and the much-acclaimed boxing documentary Fighters.

Nicholas Parsons has been an actor – he is most adamant that he is first and foremost an actor – for almost 70 years, so it’s not surprising, given the erratic nature of his profession, that he has been obliged to assume a number of alternative guises over the years from leading man to comedy sidekick to quiz master. Yet despite this, he is no chameleon. He has somehow managed to pull off the trick of being supremely adaptable whilst remaining resolutely true to himself – you’ll never catch Parsons dropping his aitches or wearing age-inappropriate clothing. Always dapper, slightly prim and a little aloof, he is the consummate professional and, at the age of 87, more in demand than ever.

When a celebrity lets their public mask slip, something wonderful and also disconcerting can happen: they can noticeably become someone else. If they’re lucky, that change can be so marked that they become just another face in a crowd.

David Frost and Richard Nixon. Melvyn Bragg and Dennis Potter. Parky and Ali. The list of seminal TV interviews is a relatively short one, and it's not about to get any longer. Alan Titchmarsh’s hopelessly mismatched bout with Prince Philip saw the Queen’s "liege man of life and limb" endure not so much a meaty grilling as an obsequious basting in Titchmarsh’s uniquely bland brand of conversational oil.

Moby (b 1965) has been a presence on the dance scene and in global clubland for two decades. He is best known for the multimillion-selling 1999 album Play which, among other things, combined lush electronic orchestration with old field recordings of a cappella blues shouters. Moby's musical career, however, began at least a decade earlier.

The Foundling Museum in Bloomsbury preserves the story of the Foundling Hospital, established in 1739 by Thomas Coram, the artist Hogarth and the composer Handel. At the end of April, American country singer Mary Gauthier performed The Foundling, a concept album telling of her birth and adoption in 1962 and the attempted reunion with her birth mother some 45 years later. Spiky-haired, in a black tee, waistcoat and black jeans, and sporting Lennon-style tinted specs, Gauthier cut a striking figure amidst the Rococo splendour of the Museum’s Picture Gallery, the lean, indomitable singer armed with a guitar and songs of infant abandonment and adult experience, beneath Hogarth’s portraits of the great and good of 18th-century London.

Christopher Eccleston’s performances have a raw-boned, visceral quality which makes him a sometimes unsettling - but always compelling - actor to watch. Since his big break in the harrowing Let Him Have It (1991), playing Derek Bentley who at 19 was the last man to be hanged in Britain, Eccleston has played Hamlet at the West Yorkshire Playhouse and worked alongside some of Hollywood’s biggest names including Kate Winslet (Jude, 1996), Cate Blanchett (Elizabeth, 1998) and Nicole Kidman (The Others, 2001).
