You're certainly right about Jerry Silverman's books, Peter. You'll find at least a dozen Silverman books in my library. My favorites are his huge Folk Song Encyclopedia and his Yiddish Songbook. For some reason, Mel Bay publishing has remaindered a number of Jerry Silverman songbooks over the last couple of years. You can still find a few at bargain prices at www.hamiltonbook.com (click here for songbooks).
