This past weekend, Midlands-born reggae band UB40 took to the Live8 stage in Hyde Park. Next year, their music may be back on another London stage nearby. Today the band announced plans for a new musical based on its songs of the past 25 years. Appropriate to the band’s own origins, Promises and Lies will receive its world premiere in Birmingham next March. But, after that limited four-week season, surely it can't be too long until a transfer to the West End where it could join the compilation musical ranks of Abba's Mamma Mia! and Queen's We Will Rock You?
