Err, if the number sold by the band as a whole is 150 million and this includes Jon's solo albums then surely it also includes Richie and Dave's respective albums too - meaning that the sales of Blaze of Glory, Stranger In This Town, On A Full Moon, Destination Anywhere, Undiscovered Soul and Lunar Eclipse have sold a total of 30 million. Even if we assume that Jon's albums did better, they probably didn't sell more than 5-10 million each.
