Bowie refused to co-operate during an impromptu interview following a performance by his band Tin Machine. As Wogan put it: "David Bowie, well he probably wasn't at his best when I interviewed him. But I thought a solid slap would have helped the situation. I didn't hit him, of course, but it came close. For some reason best known to him he came on the show unwilling to talk." Nicolas Cage appeared on the show in 1990, doing somersaults and karate kicks as he came onto the stage, and then took his T-shirt off during the interview and gave it to Wogan as a gift. Chevy Chase remaining silent through his interview.

Eventually, in 1988, she did appear on Wogan, in a special programme dedicated to her. However, a subsequent appearance to promote one of her novels led to an extremely irritated exchange with the host. Fanny Cradock made her last BBC TV appearance on the show in 1986 and jovially told Wogan his questioning was "very rude" and "very English". Patti Davis, daughter of Ronald Reagan, got into a heated argument with Wogan when he continually interrupted her and refused to allow
