Toadfrog, I once tried to catalog all the songs I knew, and I stopped counting at well over 1000.

Lest you think this is a silly exercise, I play and sing for senior facilities (of all ilks) as an occupation in addition to playing and singing for my church and with various folk organizations. One of the most frustrating things is to go blank in a jam or in an informal sing-along, not being able to think of what song to do next. That's why I decided to make a list. Someday I will probably have a (shortened) list in my gig back, alphabetized within categories. It'll save some of that aggravation of thinking of "the perfect song" after the jam or gig is over.

As for singing 1000 songs non-stop, I'll leave that to you.

PS, I'm not trying to claim any record. My point was that this "talent" of mine is not all that unusual.
