Peret - Borriquito = Music Video Performance 1971 (71012)

Pedro Pubill Calaf's song Borriquito about a little donkey became the summer hit of 1971 in Europe.

I'm not very good at Spanish but I was able to pick up some of the lyrics thanks to the audience repeating the vowels for me.
 
"A (A)
E (E)
I (I)
O (O)
you (you)
A, E, I, O, U"
 
I think this happy Peret song sounds familiar to you. What's your favorite summer song from back then?
