Over 40 years, I wrote 2 or 3 songs that I ever sang and/or recorded. Several festivals billed me as a singer/songwriter only---even though I always called myself, and indeed always was, a folksinger.
Why?
Because their audiences had ceased to show up for folksingers. They filled the joint for singer/songwriters.
Seeing the gigs dry up for the music I cared so much about, made it sad, but easier for me when my health dictated I truncate my career.
