Yes Fionn I too was "hooked" on Bluegrass having first heard the solo by Bob Yellin on the Pal o' mine track on Baez's album that we mentioned. It must have been in the sixties (early) that it was first released because I bought it in HMV Oxford Street, London before leaving the UK in 1965. I met Eric Weisberg in person at a "Bluegrass Festival" in Athy, Co.Kildare, Ireland back about 1986/7?. He did a workshop there on Nylon Strung guitar since Bill Keith was also there and, of course, took the Banjo "session". (It was outdoors, by the riverbank and it was unforgettable. I learned more in a half hour than I had done in several years of self teaching from manuals, records , whatever.) TM
