I’m not one to get misty-eyed over La bohème (unless it be a red mist of rage), but this second revival of Jonathan Miller’s production at English National Opera brought me closer than any yet to understanding the snuffling, lip-quivering reactions of those around me in the Coliseum stalls. And if it wasn’t exactly emotion that got me there, then perhaps it was something even better: sentimental delight in joyous, glorious music-making.

Last week Lulu, this week Cio-Cio San, next week the Vixen Bystrouška. These are the three exemplars of David Pountney’s “Free Spirits” – as he labels his first themed season with WNO. But it’s hard to see poor little Butterfly, pinned to a board by the cruel American sailor-lepidopterist, as a free anything. Like a trapped fly, Suzuki calls her; and if there’s a free spirit in Puccini’s opera, it might rather be Pinkerton himself, “dropping anchor at random,” as he boasts to Sharpless: not such an inspiring thought.

Rolando Villazón at 40 is back on reasonably stylish form, as far as the voice will allow him to go – which is not always up and volume-wise only just as far as the Covent Garden Balcony. John Copley’s Royal Opera Bohème is two years younger than the Mexican tenor. It burns less warmly than the faltering stove in the first act, casts a pall over collective attempts to reanimate the naturalism which is all there in Puccini’s perfect score, and needs a second interval to drag its weary bones back up the stairs to the students’ attic in Act Four.

Few singers provoke more debate than Rolando Villazón. His off-piste projects - from his Romantic exploration of the Baroque to his spell as a talent contest judge - have been much discussed over the years. By comparison, there's something strangely calm and conventional about Villazón's two latest projects: a new album of Verdi on Deutsche Grammophon and a performance of John Copley's La Bohème at the Royal Opera House. Yet you'd be foolish to ignore either.

Clearly rents in 2010 were substantially cheaper than I remember because somehow Rodolfo and Marcello have managed to find a garret in Soho of all places. And it would be easy to continue my review in this vein, poking the odd hole in OperaUpClose’s updating of La Bohème, including mentioning my temptation to shout out, “Pawn your laptop for some Covonia, mate, your girlfriend’s got a right cough on her!” But none of those quibbles were really the point of this production.

It has romantic sweep but is held firm by zealous attention to detail and while it’s hugely expansive of gesture, it’s never generalised. I’m talking about Kirill Karabits’ conducting of La bohème at Glyndebourne. I wish I could say the same for the production.

Of all Romantic operas, La Bohème is perhaps the one that responds best to what one might, for want of a better phrase, call straight theatrical treatment. It’s pure genre: no hidden meanings, no contemporary significance. “Scenes from the life”, as Murger called his book, now barely readable. Puccini’s opera, likewise, is short on continuity, long on atmosphere, very long on sentiment. Why would anyone bother with it?

A Salford lad who used to work as a bolt-cutter by day and sing in working men's clubs at night, Russell Watson started out in showbiz by singing popular hits by Elvis Presley, Neil Diamond or Simon & Garfunkel alongside a few belters from famous musicals. One night the patron of the Wigan Road Working Men's Club suggested he should have a go at Puccini's "Nessun Dorma".

Origami birds flock in graceful chorus, a dancer flutters two fans into a pulsing captive butterfly, curtains of cherry blossom descend over glowing paper lanterns, and of course a small bunraku puppet steals the show. Seven years on Anthony Minghella’s Madam Butterfly is as beautiful as ever, and – if possible – even more Japanese.

There’s a glamorous grubbiness to John Copley’s returning La Bohème that makes Puccini’s bawdy and romantic romp through the under-lit alleys of Paris’s Latin Quarter especially enjoyable. Beyond the beautifully mournful portrayal of the tortured artist and his suffocating love, there’s something devilishly attractive about it all. If anything, Copley’s direction (he is tonight celebrating 50 years since first directing at the ROH) could do with more grime under its fingernails, or a harsher and less pretty winter to really make his characters suffer in the opening acts.
