Bobby Davro: Rock With Laughter

When a performer utters the ellipsis "laygennlemen" you know you've strayed into lumpen territory, but Rock With Laughter (BBC1) takes you further, deep into previously uncharted regions of imbecility. Other "artists" have a discreet cross, or mark, on which to stand, but Mr Davro clearly requires something less subtle - a 12-foot circle with his name emblazoned across it - from which to announce that the theme of the show was Saturday Night.
