The Rock-Si-Chord quickly became popular and was used by the Beach Boys, the Lovin' Spoonful and Sun Ra. The Electra-piano was widely used by rock musicians in the late 1960s and early 1970s, including Deep Purple's Jon Lord, Frank Zappa, Rick Wakeman with Yes, and in his solo albums, Tony Banks with Genesis, Ron Mael with Sparks, Nicky Hopkins, Stevie Wonder and Elton John. Steve Winwood played an Electra-piano solo on "John Barleycorn Must Die" "Empty Pages". Dr. John played an RMI on "Right Place, Wrong Time".
