Des O'Connor is in Marbella topping up his tan. He’s only been here two days, but already he’s an improbable shade of mahogany. ‘Look at this,’ he says, flashing a generous glimpse of sun-burnished chest. ‘I only have to look at a travel brochure and I go brown. My neighbours see me and say: “Here he comes, the Singing Tan”.’ 'My wife has mentioned having another baby. But it would be a bit selfish of me at my age, even though I'm in reasonably good nick,' said Des O'Connor Here we have the measure of Des, 79, one of the nation’s best-loved entertainers: his capacity for self-mockery is matched by an irrepressible facility for fun. Inducing laughter in others is a compulsion. And in a world where vulgarity and foul-mouthed parody pass as comedy, Des’s brand of humour is remorselessly clean. He’s never said a word worse than ‘piddle’ during an act. He doesn’t go in for gratuitous insults. Once he made an unkind joke against Christine Hamilton, wife of the ex-Tory MP Neil, and felt so bad about it after he resolved never to be hurtful towards anyone again. Yet when his old friend Eric Morecambe routinely disparaged him on the Morecambe And Wise Show, he joined in the laughter. Each week, there would be a fresh assault on his voice.
