For their psychedelic version of "You Keep Me Hanging On"??
By that same token, where is the Strawberry Alarm Clock's induction?
The only thing that hampered them from being better known was a disastrous second album, a "concept album" that featured almost no music and a lot of news clips interspersed with the "Beat Goes On." This was the brainchild of their producer, the legendary Shadow Morton, and he later admitted he screwed up the band. They made three more albums, one of which did very well, but the damage was done. But their symphonic rock easily predated groups like "Electric Light Orchestra," and individually three of the four members were at one time considered the best on their instrument in the business---Mark Stein, Tim Bogert, and Carmine Appice.
