In fact, when Genesis released their Archives of some of the Gabriel-era live shows, in the 1990s, Peter actually had to go in and re-record some of the vocals, because the costumes muzzled the original vocals.
He didn’t know that during the concerts?
Gabriel’s solo work since he left Genesis was superior. Great live act that I was fortunate enough to see twice.
