I’ve long associated Rocky Horror and the Timewarp song with New Year’s. I was thinking that the movie itself was tied to New Year’s, but after a bit of research there seems to be no such connection at all. I believe the only connection is the Timewarp song coming to my mind every year (starting when I was probably 13~ish). I had seen the movie on TV for the first time when I was around 13 or so. I wasn’t fond of the movie as a whole (it did have some good moments, but it had a lot of boredom), I didn’t even sit through the whole thing (kept flipping to something else, then coming back after a while). The one portion that I really liked from the instant I first saw/heard it though was the Timewarp song (“Let’s Do the Timewarp Again”), which has stuck with me ever since (even though I have never watched the movie a second time).
I found a couple versions of it on youtube…
This one has a different version of the song than the movie had, but it’s CGI animation comes close to the movie characters:
This one has the original song from the movie, put to clips from Star Trek (done very well, unlike most such videos, which tend to be haphazard & poorly timed):
