Bob is right, having hit records is what it was all about.
When I was researching my book I did a piece (and interview) on The Constellations (the later version after they left Chicago) who of course had those fabulous productions on Gemini Star. Whether you are bored with the records or not they are great productions to listen to and stand up well on a good system, there isn't a note out of place.
Later they ended up opening up shows for Dionne for about 3 years, and their repetoire usually started with "The age of Aquarius" followed by several other equally bland popular songs. But it was great for them, regular work, TV apps, money in their pockets, touring the world, meeting other stars etc. Who would want to eat grits in the ghetto and wondering where the new check is coming from when you can have all that?
