Hey Zoob, I think you're right on about most of what you surmised except for the following:
0:00-1:34 is Goldsmith's DARK LEGACY (what ToneRow said a few posts above) and then 1:35-2:48 is Goldsmith's WELL OF DOOM 13:10 - end is not THE CHEATERS. Like you, it doesn't sound like Goldsmith to me either.
I'd also guess the remaining unidentified cues are likely to be Stevens, or possibly Rugolo, although I don't remember if Rugolo wrote specific episode end title cues. I defer to MRAUDIO's Stevens expertise to confirm any Stevens cues!
By the way, here are the Goldsmith THRILLER end title compilations I made:
ToneRow remembers correctly, I did extract and edit the M&E tracks from the Goldsmith penned episodes. It adds up to nearly 6 1/2 hours of music. I kept meaning to do the same for the Stevens episodes, but it was so much work editing the Goldsmith that I kind of shied away from ever doing it.
