Comment (by dwatteau):

 I remember hitting this problem in ScummVM, but that was many years ago.
 AFAIK, the Ultimate Talkie release rewrote the script handling this,
 because it was written in a fragile way for synchronization, or something
 like that (= some memories of mine from reading some LucasArts forum
 threads as those releases were being made).

 LogicDeLuxe's reply there is quite interesting:

 I noticed that it could also hang on the original DOS version, although it
 is rare on DOS and happens far more frequently in ScummVM. Obviously, this
 script is not written very well. I rewrote huge sections of the script in
 order to ensure stable timing, even on slow machines.''

 though, as I have reported that the timing after the dance is not perfect
 in my version yet. Investigating that is on my todo list.''

 me though, like it was already done on other problem scenes.''

 and it seems to confirm what I remember reading on the other forum some
 years ago.

 Now that our v5 implementation is very close to the original interpreter,
 it's potentially less likely to happen. But it looks like we have no real
 workaround for it and so it may still happen if one is a bit unlucky.
