What can one say about a band that has become a national institution? Despite being sneered at by critics and the arty cognoscenti alike, Status Quo have rocked all over the world for nearly 50 years since their first incarnation in 1962. The legions of Quo fans across the continents have bought in excess of 118 million records, they have made more appearances on Top Of The Pops than any other artist and have had 32 hit albums, so who needs the critics?But the mighty Quo, as they are often known, are more than just record breakers. Their deceptively simple brand of boogie-rock appeals to youngsters and oldsters alike, as any audience profile will show. Even princes have been known to tap a toe again and indeed again. Although their record sales are impressive, the real home of the band is live on stage. Touring endlessly, their high-energy shows always bring the audience to their feet, heads nodding and air guitars akimbo. Guitarist Rick Parfitt had a quadruple heart bypass operation in 1997 but this hasn't slowed them down down. They have played on an aircraft carrier, in forests and even managed four gigs across the UK in 11 hours and 11 minutes. In 2009 they stormed the Glastonbury Festival, an event not normally associated with classic rock. Possibly their most famous moment was opening Live Aid in 1985, a task that no other band could have pulled off with such aplomb. They will, for the forseeable future, always be the band to provide whatever you want.
