This was sung by Joey Covington with the Dead and others from the Jefferson Airplane on 7 September 1969. In fact all he manages is a garbled version of the first verse, repeated twice!
Blue moon You saw me standing alone
Without a dream in my heart
Without a love of my own
Blue moon You knew just what I was there for
You heard me saying a pray for
Someone I really could care for
Blue moon
You saw me standing alone
Without a dream in my heart
Without a love of my own
Blue moon...
Without a love of my own
