This is a rip from an original 1991 Toejam and Earl cassette tape. It was written and performed by Toejam and Earl designer and creator Greg Johnson.
This rap was featured in the NTSC (USA) Sega Genesis Toejam and Earl manual. For some reason this rap didn't appear in the European Sega Mega Drive manuals.
This promotional cassette tape was bought from Sega Visions magazine.
