this happened in the early 70's. video and film equipment at that time was very expensive and it was B/W. maybe a few Super 8 films are available but haven't seen one from this venue yet.
if some film is available, I would love to watch it.
btw, there's an Eddie and Charlie Palmieri b/w 10 minute film available in YouTube performing live "Muñeca" in Central Park in 1972 (youtube.com/watch?v=7QqVixG1foo). the film doesn't catch the song entirely but it gives you most of what happened there. this was shot by Izzy Sanabria and Walter Vélez. both were at that time in charge of most Fania graphic work, including most of the album covers.
from the same concert, "Vámonos Pa'l Monte" is also available (youtube.com/watch?v=uCIdMzBPOts).
