Hi everyone! I need to find the last song from this video that I am recently enjoying. Hope you can solve the mistery people. Song starts at 7:03. Thanks =).

Ohh nobody knows. I guess it's a European band of 1973 beacuse the majority of the songs from that video are from that year.

There are at least 3 or 4 different songs/bands on that clip. None are complete, but that's not just one song.
