Jimmy Rabbitte is back. The man who invented the Commitments back in the 1980s is now 47, with a loving wife, 4 kids... and bowel cancer. He isn't dying, he thinks, but he might be. Jimmy still loves his music, and he still loves to hustle--his new thing is finding old bands and then finding the people who loved them enough to pay money online for their resurrected singles and albums. On his path through Dublin, between chemo and work he meets two of the Commitments--Outspan Foster, whose own illness is probably terminal, and Imelda Quirk, still as gorgeous as ever. He is reunited with his long-lost brother, Les, and learns to play the trumpet.
