Graham Gouldman won't be back with Ringo Starr's 2019 All Starr Band. And the decision was his.
He says that it was "due to my 10cc commitments. In fact, we’ve never been busier... I do hope, and Ringo knows this, that I will be able to return to the fold at some point in the future. I had an absolute blast with Ringo and all the members of the band."
Not only will 10cc have a busy schedule across Europe in 2019, but "there is a possibility of 10cc coming to the U.S. next year."
