This is from wikipedia:

A visit into an antique museum was the inspiration to write a romance metaphor, which took about four months to finish. Composed by Vinnie Barrett and Bobby Eliit (both collaborated on another Philly soul ballad "Love Won't Let Me Wait" by former Delfonics member Major Harris.), when record producer and guitarist Norman Harris heard "Sideshow", he said that should be recorded by Blue Magic. It was released on the album Blue Magic, became one of pop music's most affecting ballads and sold over a million copies, going to number one R&B and number eight pop in the summer of 1974. The follow-up was the similarly themed "Three Ring Circus".
