Billy Beck the keyboardist for the Ohio Players during their heyday in 70s plays their classic tune, Funky Worm. I can't tell which Casio he's using. It looks like a premium model CTK. Anyway whichever one it is, there can be no doubt that he's definitely turning it out. See a full_length recording of his interview and mini_concert when you Google, Deborah Benton Valley Gold 🕶️🎼🎶🎹😎
