From wiki
"Sesame Street" by Blowfly, interesting testimony of breakbeat science as the breakbeat is reconstructed from various places with solo drums in the song. Also known as "Helicopter" break after "The Helicopter Tune" by Deep Blue, which is the common second-hand source of the reconstructed sample.[10]
Apparently the Helicopter has some extra high hats and cymbals and is a better source to sample it from. As per my understanding anyway.
