I perform several songs with mid song breaks, Run Around Sue, Margarettaville, and others. Some, such as Old Time Rock $ Roll, Hot Hot Hot, etc...,have a segment where nothing other than the drums are playing, while you continue to sing. The style's default break usually works fine for the first group, while the second group merely requires hitting a single button, the Accompaniment On/Off. The secret is to hit this button twice. Then, when you want to get out of that mode, hit a fill and press a chord with your left hand. Piece of cake.

Cheers,

Gary
