I remember that episode.
I’M OLD !!!!!!
Didn’t The Grateful Dead invite people to record their concerts ?
Now that may be a good or a bad thing depending on how you feel about the band!
I don't consider myself a super fan but I do randomly listen to their concerts from time to time. Each concert is unique and there are usually pleasant surprises, be it an extended jam of a familiar song or a cover version of another song you never imagined they'd cover, such as "Iko Iko" by The Dixie Cups.
I believe circulating "free" recordings of live concerts help promote the band and thus actually increase their record sales as well as concert attendance.
