Bud & Travis - So Long, Stay Well (1963)
American folk duo well respected by their musical peers, cited as influential artists, but that didn't translate into big record sales. Bud & Travis translated other works and made them their own, were very adept at covering Spanish tunes, and even wrote some of their own music. In concert they would even infuse comedy routines which predated The Smothers Brothers. Here is a fine rendition of Rod McKuen's "So Long, Stay Well".
