Yes it's possible and it happened to me to some extent. I grew up with folk music, especially what I remember as a youngster in the 50's, I suppose what was left over from the 40's and of course the folk music of the 60's, ie: Peter, Paul,& Mary; early Bob Dylan; Pete Seeger. I remember religiously watching Hootenanny every week and desiring to learn guitar and be in a group like The New Christie Minstrels. And yes, Barbara, I DO remember the much too short lived TW3. I think David Frost got his start in TV on that show. (I wonder if there are any tapes of TW3 out there somewhere?) I started collecting blues albums like Mississippi John Hurt, Larry Johnson, Roy Bookbinder, Rev. Gary Davis... I also matured as a folkie with the more recent folks ie: BMT, Stan Rogers, Bill Staines, Claudia Schmidt... Only in recent years I've been exposed to early Grateful Dead, Hot Tuna, Rolling Stones, etc., through friends and co-workers and I have an appreciation for these groups now that I never had before.
