Some of my examples are dead. However:
Doris Day (need I say more)?
Diana Rigg (exuded warmth and charisma)
Rachael Stirling (Rigg's daughter. Very like her mum)
Mick Fleetwood (happiest drummer in the world. Even without the coke looks like he's having a blast)
Victor Garber
Rik Mayall
Robert Englund
Terence Stamp
Patrick Swayze
Both the 'Julies'
Laura Kennedy (Trott)
Christian Lorenz, AKA 'Flake'
And a big +1 for Korn (especially Jonathan's kilt)
My ex's sister was a dancer working in TV back in the day and trained at Italia Conti. She was a friend of Debbie McGee and said both she and Paul Daniels were lovely people.
She also mentioned Rolf Harris and his reputation with those who worked closely with him. Sadly I was not surprised.
