OK, more 60's: This Beatles-inspired 1967 Bee Gees tune was their first U.S. release and their first chart single in the U.S. (#14) and the UK (#12). A trapped man yearns for his wife as his life fades away. The "mystery" opening chord is played by Barry using an open D tuning but playing a conventional A-minor chord shape.
Yesterday's answer: "Teach Me Tonight" by The DeCastro Sisters. From Dr. Dan Rogers: "I wish there could have been a recording of the song by April Stevens; she would have burned it up with her "Teach Me Tiger" sort of voice. But the DeCastro Sisters gave it a really nice sound. Love that song!". Me: Pretty risque lyrics for those days!
