Ethan suggests calling his friend Baz to help play any guitar solos. Baz is willing to help, but has already checked himself into rehab. Baz meets a fellow alcoholic, Steve, in rehab, whom he discovers has more than a passable voice. He suggests bringing Steve along to the rehearsal sessions as a backing singer when both of them have dried out, and the rest of the band agree.
However, once Baz and Steve arrive at Seth’s mansion in deepest Wales, a tragic event occurs that none of the band could have ever foreseen and which threatens the commencement of what will now be the band’s farewell tour.
