Part of a Rotosound press release:
Dennis Dunaway, co writer of “School’s Out”, has used Rotosound RS 66LD 45-105 Swing Bass strings ever since. In fact the Fender Custom Shop will soon announce a limited edition of the Billion Dollar Bass, which is a remarkably detailed replica of Dennis’s original 1970 Fender Jazz Bass that he used on the majority of the Alice Cooper Group recordings. This was the first bass that he used Rotosound Strings on, to record "School's Out."
