“There’s no place like home… there’s no place like home… there’s no place like home…” A wish became a mantra and then became a happy ending, when Dorothy wiggled her ruby-red shoes in the MGM movie version of L Frank Baum’s fairy story. But this documentary didn’t even get to the most watched film in the history of cinema until its closing 10 minutes: perhaps because its makers were concerned that if they’d called it “The Story of L Frank Baum” it wouldn’t have found an audience.

John Cage, the focus of an adventurous three-day mini-festival in Bristol, is possibly one of the most influential figures in 20th-century culture. As much a practical philosopher as a composer of note, he made artists, writers and musicians think about the nature of chance, our place in nature and the role of the subject in the creative process.

Captain Scott's doomed 1910-1913 expedition to the South Pole has become one of the enduring myths of the later British Empire, a paradigm of pluck, grit and a refusal to surrender in the teeth of hideous odds. Subsequently, some historical revisionists have reached a different conclusion, that Scott was in fact an ill-prepared amateur who committed a string of fatal errors.

I prefer "living room", but I have a friend who insists on "lounge". For some reason that probably goes deep into the psyche, I cringe at "sitting room". Same goes for "front room". As for "reception room", I’ve only ever seen that in the windows of estate agents. "Parlour", too, is a rarity, confined now to TV period dramas, which is exactly where "drawing room" seems to be heading (or perhaps I’m not mixing in the right circles). And anyone who calls it a "dining room" should surely be consigned to lonely TV dinners in perpetuity.

“Love is no solution to life,” declares a line from Clifford Odets’s 1938 drama; and in straitened times, then and now, it’s a sentiment that carries considerable doleful weight. And yet every character here is in desperate search of that elusive something to elevate the banal business of day-to-day existence – a personal rocket to the moon. Without it, they are trapped in endless Monday mornings, soul-destroying work that doesn’t bring in enough to pay the bills, and relationships in which they turn into “two machines, counting up the petty cash”.

Weeds, memorably, have been described as merely being plants that grow where we don’t want them. Walking through the Wellcome’s fine new exhibition, we can conclude that the “dirt”, too, is merely material appearing out of its appropriate location. One man’s waste is another man’s fertiliser; one civilisation’s dust-heap another’s city foundations. Children first planting a window box learn that “dirt” is alchemy: stick in a seed, out of the dirt comes dinner.

What ever happened to Ida Kar? If the question is not quite on the level of What Ever Happened to Baby Jane?, perhaps the answer is more interesting, if less melodramatic. Ida Kar - born Ida Karamian in Russia of Armenian parents, resident of Cairo, Alexandria, Paris and Soho, the first photographer to be given a retrospective at the Whitechapel Gallery in its heyday under that curator of genius Bryan Robertson – is now, all too often, known as “Ida Who?” even by those who should know better. So, What Did Happen to Ida Kar?

I have thus far been a bit wary of the Janelle Monáe hype. It's only natural: when an attractive young performer is taken under the wing of megastars like Outkast and P Diddy, and drenched with media acclaim that pronounces them an artist on the level of Prince, all on the basis of a few download tracks and one album, one bristles. And when that album is heavily conceptualised and crisply produced but more full of overt retro references than it is instant tunes, the suspicion only grows. Live reviews, meanwhile, suggested that there might be something more stage school than old school about her soul stylings. I really didn't have many expectations for last night's show.
