“Baby Its Cold Outside,” Dean Martin, 1959

For all the cock and bull about this classic being (to borrow a friend’s term) ‘rapey,’ this duet was written by Frank Loesser in 1944 and originally performed by he and his wife, Lynn Garland.  Lynn was furious when Frank sold the rights to MGM; she considered it to be ‘their’ song.  Curiously enough, the ‘mouse’ part is sung by a chorus in Dean’s rendition.

It bears mentioning that the part sung by Dean is marked as the ‘wolf’ in the sheet music. /shrug
