Prime 5 is a recording by Ween. It was released in 1988. It is a sort of greatest hits compilation, comprising tracks from their first five homemade cassettes: Mrs Slack, The Polish Lightbulb Joke, Mike Banks, Kim Tulio, and John Ward. This information came to light in early 2017 when the tape was re-compiled and uploaded to youtube.
Tracks 01-08 come from the Mrs. Slack cassette. Tracks 09-11 come from The Polish Lightbulb Joke cassette. Tracks 12-18 come from the Mike Banks cassette. Tracks 19-24 come from the Kim Tulio cassette. Tracks 25-30 come from the John Ward cassette.
