RIP David Cassidy who died yesterday, aged 67. I don’t think any solo performer ever caused more teenage hysteria he did. Thousands of girls besieged Heathrow Airport when he first arrived here in 1972. And thousands more ran screaming after him wherever he went. Many years later, he came to London to star in a West End musical and I got him in to do a voiceover for an American beer commercial and he was great. Nothing like the dull abstemious Osmonds, he was every inch the rock star. Cool, charismatic and charming, he was full of stories of drink, drug and groupie-fuelled excess. The sort of person whose life makes you feel like you haven’t lived at all. Donny Osmond will probably live to be 100 but I know who I’d rather have been.
