There are a million versions of this tune but for me Summer Samba is an instrumental played on a Hammond organ. It sounds like such a light weight, puff piece, but that belies the tune's amazing structural complexities, from the melody, to the chords, to the deep improvisional possibilites, it's one heck of a tune. This version is clocked to the famous 1966 Walter Wanderly instrumental hit. The only variation is the Intro and tail end, they don't ranslate from organ very well, but they are close. Tchau.
