There was a satellite feed of Drew McIntyre's debut where we got to see his entrance and he came out to this pretty great theme song that sounded like it was sung by the lead singer of the Police.
No footage of this exists anywhere.
There was a time a huge collection of rare unreleased WWE themes were put on Youtube but for some reason they all got wiped, including that one.
It seems like in general, rare wrestling theme hunting and discussion is a relic of the past.
