Re T.J. HOOKER: what more can you say about Mark Snow’s theme song, which is used incessantly throughout each and every episode?
Here's the version of the theme that was used after Heather Locklear and James Darren joined the show. They had to let it run to a minute and a half to include the expanded cast.
I prefer the original version, which ran only a minute, has a punchier intro, and features Hooker's leap onto the school bus.
