"Williams marks the early days of Indy's adventures at the outset of the film with a playful theme that shares all too many elements in rhythm and instrumentation with his obnoxious Ewok music from Return of the Jedi."
Obnoxious? Well, if you didn't associate it with the Ewoks, would you still be of the same opinion? I also don't think that this LAST CRUSADE portion is annoying, at all. Completely the opposite.
