WHEN Rolf Harris was last at the Glastonbury festival, 130,000 people came to see him open the main stage – the largest number ever for an opening act, he tells us, with great pride.

Tonight, Rolf comes on before his own opening act, with jokes, a wobble board and a reminder of his last Nottingham gig ("Rock City – I was terrified!"). His first hit, Tie Me Kangaroo Down, gets an extended outing, including a country version replete with Jew's harp and much audience oohs and aahs.

The less said about the comic who follows - a man who thinks blowing up a condom over his head until it explodes is hilarious – the better.

After an excruciating half hour, Rolf returns for Jake The Peg, but things go wrong. His three legged orange trousers fall down. "That's never happened before," he insists. Judging by the alacrity with which he leaves the stage, I believe him.

The 80 minute main set demonstrates why Rolf's devoted audience love the 81-year-old so much. Sun Arise brings on the world's biggest didgeridoo. He gives us the story behind Waltzing Matilda and a Christmas song where kangaroos substitute for reindeer. Then, backed by the didgeridoo, he spends twenty minutes chatting and painting a giant canvas of Ayer's Rock. It makes me think how, with all those sixties TV shows, Rolf has a strong claim to be the founding father of Brit Art.

The painting's a mess, and that blue paint will be hell to get out of the stage's wooden floor ("we should have put down sheets, shouldn't we?") but it hardly matters. Two Little Boys rounds things off, then it's back for a rousing Stairway To Heaven and a touching Goodnight, Irene.

This modest, hard working legend more than earns his standing ovation.
