Speaking of B3 schtick, Billy Preston was great at it. There is a favorite organist’s trick of holding down a hight note and letting the sound go on and on. The crowd goes wild. Maximum effect, minimum effort. Billy had a little wedge that he would stick in the keys to hold the note. Then he would clap both hands over his head. The crowd goes wild. To see him do this check YouTube and Eric Clapton – Have You Ever Loved A Woman (Part 2). At about 7:09 see Billy’s schtick.
