"Sorrow" is an original song by the The McCoys from 1965, which became a big hit in the UK in a cover version by The Merseys in 1966. Bowie picked up this song again in 1973 for his covers album "Pin ups".
When I transcribe a cover version of a song, I'm always curious about finding out how the orginal song sounds and therefore I also transcribed the original bassline from The McCoys version:
