Classic Rock magazine (no. 181, March 2013) just made a list of "250 Lost tracks you must hear before you die". One of the least lost songs on this list is Robert Wyatt´s "Sea song"!
The snooker star Steve Davis chose the prog tracks to be included, and he obviously likes "Sea Song" a lot. He writes : "His (R.W.´s) vocal is terrific, and his take on a love song is unusual, beautiful and gratifyingly strange" (p. 55).
Well said, but "Sea Song" a lost track? I think not! Here you can hear it with Robert Wyatt and friends, and the magnificent Unthanks.
