What do you guys think, could it be possible that Slim Pickens is going to be an updated version of Tonight I Do? You know, the song from the 1986 tapes, that starts out with When Johnny Comes Marching Home.
It's the same melody that was used as a recurring motif in Dr. Strangelove, which is referenced in Slim Picken's full title. I'd personally dig it.
Sorry if this theory has came up before.
