A couple of themes, here.
Conga drums -- I really miss 'em. It used to be that every other band would use a conga-player to fill in the rhythm section. Three of the four selections in this batch have that. Drummers need to get the hell out of drum circles and join real bands.
All 4 of these groups could have been represented by a number of other songs; they were all got played a lot on FM radio in the early '70s (probably because they all played frequently at Bill Graham venues during that period). The Fleetwood Mac number, here, was a particularly difficult choice -- it probably should have been "Oh Well", but "Coming Your Way" has been drilled into my brain slightly less, and, well... the congas.
It was the beat! The beat!
