Guitarist Pete Townshend may have to leave the Who if a new device doesn't improve his tinnitus, a painful ringing and buzzing caused by years of exposure to high sound volumes at gigs.
"If my hearing is going to be a problem, we're not delaying shows. We're finished," Townshend told Rolling Stone. "I can't really see any way around the issue."
He'll make the decision whether to call it quits after testing a new in-ear monitoring system during the group's next gig in London at the end of March.
"It's a good test of Pete's hearing," Who vocalist Roger Daltrey told the magazine. "We won't know until we try."
