...some of the reviews here seem to miss that point. The Sons recorded for Columbia and Ariola, but before that they were on Capitol where they recorded "Loosen Up, Naturally" "The Sons" and "Follow Your Heart" which is where these tracks originate. If you can't afford the high prices for those (all out of print in the US) this is a very fine alternative. You get 2/3 of Loosen Up, and over half of The Sons, and two tracks from the admittedly less substantial Follow Your Heart. I'd say that's a pretty good deal. Why people insist on comparing the Sons to Chicago and B,S & T, I don't quite get. They aren't anything like them. They have horns, yes, but so did lots of groups. You could make a case for a comparison to CTA; it's kinda sorta similar,especially the guitar playing, but the Sons carry a more positive approach (more West Coast, I guess) and are funkier, while Chicago kept getting "popier" (not an insult btw). No comparison to BS&T.
Any CD that has "Freedom", "Love of a Woman" and "Boomp Boomp Chomp", not to mention "Everywhere" and "1982-A" would be worth it, even if there weren't any other tunes on it. This is a great intro to the Sons of Champlin, and the rate is still cheap (under $10 for a used copy) so give it a chance. You'll be glad you did.
