WhenI first met Utah Phillips I realized that often what I said between songs was as important as the songs themselves! Bruce ("Utah"), by judicious use of humor, could get an entire audience of Newts (Gingriches) singing along on "Dump The Bosses Off Your Back". That's when I started to talk on stage.
This allowed me to sing for audiences that weren't into traditional American folksongs at all (like those retired tour groups I often sang for during ten years of gigs aboard steamboats on the Mississippi River)and actually be able to have them enjoy themselves---maybe learn something too.
Later, when physical problems caused my hands to go numb, I could stop, often between verses, and tell a pertinent tale or even a joke. This allowed me to rest my hands; it also allowed me to perform at least 4 or 5 years longer than would've otherwise been the case.I became an entertainer & not only a folksinger---from necessity!
