I don't have the capability to 'scan' our list of songs that we can play w/o music. There are some that a couple of us hafta use lyric sheets for*, but at last count, including some jazz and bossa nova standards for when we need to do a 'dinner' set, we have ~250 songs to choose from, depending on what the crowd wants to hear. We aren't doing a 'show', we're hired to play for dancing. Or, as I sometimes say-with apologies to Spike Jones-"Dinner music for people who aren't very hungry."
*what a drag it is getting old. Remember, "A mind is a terrible thing."
