Thank you very much mate ! I love this song , it's one of those pearls , te quirky intro is part of Spinetta's arrangement , the original was much simpler :) !
Luis Alberto Spinetta is always in my top list of musicians, he passed away a couple years ago but left back 40 albums of pure awesomeness , he was a visionary . He's the guy on the red guitar and Fito is the 2nd singer ( and composer of this tune ).
