Fred Young did voice characterizations on this game. Designer Wally Welch told us that John Boyston was the lead electrical engineer for this game and Jim Studnicka did some miscellaneous drafting and detailing of drawings. Both are listed in the personnel credits on the apron. Michael Gottlieb told us that Al's Garage Band was based on people he knew: Al, Gloria, Delmore, and Dr. Skins. Only one character, Stitchy, was not a real person. The game in the manufacturer's flyer shows a VUK at the end of the horseshoe ramp in middle right playfield at what would be the "top lock". This VUK was subsequently removed by the manufacturer. Reportedly, twenty games were made with this top lock VUK. This quantity has not been confirmed by us.
