The story is that John Bonham was so nervous about going on "Alright Now" as Billy Connolly's guest that he almost backed out at the last moment. Convinced to relax and that it would be fun, John submitted, though hesitated to engage with answers longer than a word or three, even though he was being interviewed by his friend, Billy. This was the last television interview he did as it was only filmed a few months before his death - September 7, 1980.
