Again, the rules are, there are no rules. You can post your favorite old singer, band, trio, quartet, orchestra etc.
I'm partial to Billy Joel (singer) The Who (band) Genesis (quartet/trio) and actually listened to ELO (Electric Light Orchestra) for awhile so I fall under all of the above. Your turn.
