Sympathy vote time is over. After Edwyn Collins suffered two cerebral haemorrhages in 2005 his comeback album, 2007’s Losing Sleep, was greeted with ecstatic reviews. It was a certainly pretty good, but maybe critics, being the old softies we are at heart, were slightly swayed by our unbridled joy at the fact that the former Orange Juice frontman was simply back in the game. So the new album, Understated, is the real test of whether Collins can still cut the musical mustard.

How much more of a melancholy experience walking round this exhibition would have been if its subject hadn’t just sprung a new album on us that’s so suffused with energy and life. It’s meant that the exhibition's title - David Bowie Is – feels like a genuine statement of fact rather than just wishful thinking, at least in the literal sense.

Glam. Were you there? If so, what was it all about? You might come up with a list: Roxy Music, Ziggy Stardust, shiny flares, Sweet, shaggy hair, the ubiquitous platform boot, T-Rex, glittery eye-shadow, lip-gloss pouts (on men). It was the era of dressing up and gender-bending as fashion statement, though it’s also true that the glamour in Glam Rock was more glitter paste than gold. Some of it remains pretty cool, but unlike the Sixties you probably wouldn’t want to go back there, or at least for no longer than it takes to get round this exhibition, though Glam!

“Five years,” said former Mott the Hoople fan club president Kris Needs of the band’s lifespan. “That’s how long the Kaiser Chiefs have been around, but who cares?” It seemed an unfair measure. Mott split 39 years ago and the Leeds quirksters are still going strong. But in terms of stitches in rock’s rich tapestry, Mott’s, like the Kaiser Chiefs’, probably wouldn’t darn a sock.

Suede, led by the arrestingly beautiful Brett Anderson, was one of the finest bands to come out of the UK in the first half of the 1990s. Their eponymous debut album, released in 1992, won the Mercury Music Prize.

Let us go now to a foreign country. To the foreboding concrete tunnels and rooms of an RAF early-warning facility under the Sussex Downs in the early summer of 1973.The Lower Sixth has somehow procured the space for an epic late-night party. Cheap beer and cheaper cider is drunk. Cigarettes are smoked, self-consciously. Flared jeans and cheesecloth shirts are worn under Afghan coats, not with panache.

The Dark Side of the Moon and Frankie Howerd’s Roman-era television farce Up Pompeii! aren’t as unlikely bedfellows as it first seems. The link comes from Clare Torry, whose voice opened the show each week. She also provided the unrestrained vocal on The Dark Side of the Moon’s Rick Wright-penned “The Great Gig in the Sky.”

I’m embarrassed to admit that I’d never listened to The Dark Side of the Moon until a few weeks ago. I’ve heard loads of other esoteric vintage pop, most of it terminally unfashionable and deeply obscure. Growing up in the Seventies and Eighties, I was vaguely aware that Pink Floyd had hit an uncool patch and the album passed me by. I’ve now made up for lost time. Through vintage speakers and scratchy second hand vinyl. Via weedy iPod headphones. In the car, en route to Sainsburys.
