Dirk Diggler supposedly records the song "The Touch" before his death in 1981. The song was actually written for The Transformers: The Movie (1986) in 1986.
I am assuming that you can infer the direct correlation between this film, and Boogie Nights. Dirk Diggler is the central character in each, and Jack Horner reappears in Boogie Nights as well. This is Paul Thomas Anderson's early work, but I'm sure we are all happy it progressed into the amazing film it did. Due to its very obscure nature, good luck finding it.
