I can't say, really, but Wills seemed to like stream of consciousness commentary. His nonstop narrations were just a part of his charm, and probably an annoyance to his hard-working soloists and patient recording engineers. He simply doesn't shut up, as if his enthusiasm cannot be contained. In one cut, he delays the fade-to-black in order to say "Domino" quite deliberately, as if it were relevant to the lyrical content. It wasn't: most likely it was unrehearsed and just fun to say at the time. Some of it is a sort of Texas jive from his ethnically varied influences; some are square dance-inspired remarks. A favorite of mine is his introduction of a band member: "A man after my own heart...with a razor."
