We dusted off our air guitars and left our dignity at the door, for the mighty Quo had come to town to rock our worlds.

Like Japanese soldiers on some remote Pacific island decades after VJ Day convinced the Second World War is still raging, for the Quo, it will always be 1973.

From the back, unable to see the lines time has worn into their faces, it almost could have been.

After a short-lived psychedelic incarnation in the late Sixties, they stuck to the 12 bar blues rock form religiously.

Such brazen disregard for musical vogues has see them sell more than 100 million records and enjoy nearly as many UK hits as The Beatles. Classic tunes have included Caroline, Rockin' All Over The World, Whatever You Want and Down, Down.

Just take the current album Riffs, in which they cover all manner of artists and make them sound like Status Quo. They could do a rendition of a Debussy cantata and it would be no different.

Their real spiritual heirs are the Ramones but they were self-consciously dumb. The Quo are effortlessly stupid and it's hard not to love them for it.

Status Quo are good at what they do.

They should be, of course, it has consisted of playing what is essentially the same song for more than three decades.
