“If you’re not with, the one you love, baby, love the one you’re with.”
Maybe this is Joe:
“When I’m not near the girl I love
I love the girl I’m near
“When I can’t fondle the hand I’m fond of
I fondle the hand at hand
“When I’m not facing the face that I fancy
I fancy the face I face
“When I’m not close to the kiss I cling to
I cling to the kiss that’s close”
(Finian’s Rainbow)
