AC/DC bassist Cliff Williams and former John Entwistle Band drummer Steve Luongo met at a hurricane relief concert produced by the John Entwistle Foundation in 2005. The year that followed found Cliff and Steve jamming together when the opportunity arose. In 2007 they were joined in the studio by guitar virtuoso Mark Hitt and AC/DC vocalist Brian Johnson for a bit of fun. In the months that followed this group of musicians did what all musicians do. They wrote and recorded music together. In the spring of 2007 Cliff and Brian agreed to lend their talents to a fund raising tour dubbed Classic Rock Cares. The proceeds from the tour will go to the foundation's primary mission of free music education and instruments for underprivileged children through the public library system.
