He's gotta be a multi-millionaire and the wealthiest of anyone from the band. A song like Babe has been put on hundreds of compilation albums over the decades and I think he still has a share of Styx under his belt where he get a cut of the business in some form... plus they perform songs he wrote.
Now that he's sold his publishing and recording rights, some of that has probably changed but he also got a lump sum payout.. and it was probably not a small amount of money... and he sold his Florida home (asking was $2.8 Million)
