Carlos stepped back from live and studio commitments several years ago at the request of Rick Nielsen, Robin Zander and Tom Petersson, but insisted that he remained a part of the band business.

The matter went to court in 2014 but was apparently settled last year, with Zander commenting: "We've had our differences, but we're all settled up now and hopefully we can forget about that era."

Now Carlos says: "Being reunited for that final performance was an overwhelming honor that I'm grateful for. This should be a time of celebration, we're in the Hall Of Fame, Cheap Trick have a new record out, and I've got a new solo record coming in June. But it's hard to celebrate when the other three shareholders are in all the papers and on the radio calling me names and saying things that aren't true."
