Devotees, who paid up to $120 (GBP66) to see the Sweet Caroline singer live at the city's Value City Arena, have demanded refunds from the venue after many walked out after a croaky Diamond struggled through his hits.
The 67-year-old singer is now considering performing at the venue again to make up for a terrible gig.
In a post on his website, Diamond writes, "Please give me a few days to figure out a way to make it up to you. I haven't let you down before and I won't let you down now."
