Bobby You're A Rich Man?

Driving around a bit ago I had the radio going, and one of the local stations played "Heartache Tonight" by the Eagles. The DJ mentioned that Bob Seeger co-wrote the tune, and it got me thinking about how well off Seeger might be. Seeger hasn't had a hit in a long time, but his back catalogue must generate a good bit of income. A number one hit like "Heartache" alone must generate a nice income even if he was a co-writer and not sole composer. Seeger's Greatest Hits album alone has sold 8 million copies to date. Chevy using "Like A Rock" in their ads for years must be worth some major coin as well. But of course as anyone who knows much about the music business is well aware even being a hit songwriter won't make you rich if your contracts are bad or you have deficient management. I've never heard of Seeger having such problems, so I'd bet he's not hurting even if he isn't a chart topper anymore.
