"Red Red Wine" is a song written, performed and originally recorded by American artist Neil Diamond in 1967, later to become a best-seller for the band UB40.
Roger sings "Red Red Wine" as he enters the smith basement in "The Shrink" while listening to the song on a set of headphones, as the family tires to get his attention from Stan's model layout where he has shrunk everyone in order to keep them safe from the outside world. In the process, he drops and breaks the bottle.
Red Red Wine...
[The family sees him and tries to get his attention, as he proceeds with his own version of the song]
Red red wine you make me feel so fine
Monkey pucka breeze upon the sweet of lime
Red red wine you give me whole heap of things
Whole heap of things make me do my own thing
