Frank Iero, previously a member of alt-rock heavyweights My Chemical Romance, stepped out on his own as Frnkiero Andthe Cellabration on his solo debut, “Stomachaches.” Here, with a little help, he offers an acoustic version of “She’s the Prettiest Girl at the Party, and She Can Prove It with a Solid Right Hook.” That may be a mouthful, but he pulls it all off with ease.
