Live 1975... https://www.youtube.com/watch?v=hMHjjvLjtAM
My favorite memory of this song was at a party. My friend was mixing up drinks behind the bar. During the slow part of the tune he was preparing about 20 mixing glasses. When the tune finally kicks into gear at about the 5:05 mark, he starts swinging and mixing all these with the rap of the music and starts handing out drinks. Guess you had to be there. Great times.
