Change Band is performed by typing /changeband . It allows an entertainer to change what song the band is playing without having to stop the music and start up again. Holos and droids only recognize band and (dance) troupe commands, such as change band, and will not emulate your regular commands. If you use holos or a playback droid, this is a must know. See Entertainer Songs for a complete list of songs a true master musician can play. --Three songs are not freebies, and require you to earn them. Two of them are rare.
