As for Madonna . . . 'I think she's terrific. When I'm chatting to her, she's just normal, the opposite of grand. We'll meet in a restaurant with friends. Or hang out at a party. She's always interesting and interested. She's smart as hell and keeps her eyes peeled. She misses nothing.'
She adds: 'Gaga and Madonna have realised the value of shock. But why not? You need to do anything you can in this business to get noticed. And they've both done it brilliantly. 'In a way, I started that with the Sally Bowles look, the cropped black hair, the lashes. It was a look that became important. It went round the world.'
'I try to live in the moment and appreciate everything as it happens'
Liza credits Charles Aznavour as being her biggest professional influence. 'The first time I saw him perform, I don't remember breathing for two hours,' she recalls. 'Every song was a story. The acting within each song was phenomenal, something I've tried to emulate.
'I never thought I sang that well. I still don't. My sister, Lorna [Luft], has a better voice than me. But I can act out what I'm singing and maybe that's what people respond to.'
Liza is firmly back in her groove. 'Are these good times?' she asks. 'Man, these are great times. I no longer trust as easily as I used to, but I've become more knowledgeable about picking the people around me.'
