This Week in Baseball (abbreviated as TWiB) had two theme songs. The opening theme was "
Jet Set", which was also used as the theme song for the original version of the game show Jackpot. When Fox brought TWiB back to television in 2000, a slightly different version of Jet Set was used as the opening theme. The closing theme, and the one fans most associated with the program, was "
Gathering Crowds". Both themes were composed by Mike Vickers, a former member of the original Manfred Mann band, though he's credited under the pseudonym Patrick J. O'Hara Scott for Gathering Crowds.
