I had for many years ago a track that had a sample from Jane Fonda I think.
The sample goes "And 1,2,3,4,5,6,7,8 and 1,2,3,4 "etc.
The sample is repeated most of the time to sync with the track.
I think it is made in the late 90´s.
Does that ring a bell somehow ??
You can also use the track to a great work-out
