This version of Welcome to This World was actually taken from the Primus album Pork Soda, so I did cheat a little. The song is used in Brainscan by The Trickster who puts it on and does a little dance.
Forgot about this song and movie. Popped in my head last week. Watched it Monday on prime and haven't been able to get song out of my head since. Thank you for posting. Primus was a staple of childhood.
I also heard this song watching this movie funny how you only hear like 10 sec of it during the movie but I remember feverishly fast forwarding the movie credits to find out who sang it no google back then. def turned me on to primus
