'Shake A Leg'

The song 'Shake A Leg' that appears in this movie was written by Edward R. Hoerner; as of this writing, the song and writer are not credited on this movie's IMDb page. It caught my ear because the same song was also recorded by Sea Level (an Allman Brothers Band spinoff) for their debut album the following year. I wonder how many more incarnations it had in the '70s and '80s? (Through the last few decades there have been a number of other songs with that same title.)
