Hold on to your gag reflex; I write in the throes of a serious case of hero worship.Last night I went to see Randy Newman. I was sitting just 6 rows from the stage and the Steinway and the shambling man himself with his bespectacled 'froggish' face. You could not have come across a happier camper than me when he started on the first bars of 'Birmingham'. You could not have.
