If nothing else, Alan Janes's 1989 tribute musical proves that Buddy Holly--who died in a plane crash almost 50 years ago--has staying power. Though the book is criminally slim and obvious, Holly's music carries the show. That is, if the musicians are good enough, and they are in this high-intensity staging by Janet Louer (who choreographed the show's 1992 touring edition). Josh Solomon, vulnerable and earnest as Holly, both credibly imitates the singer-songwriter and puts a new spin on some songs, especially the delicate "Everyday." The big second-act production numbers bury Solomon's interpretation, but Daniel J. Rosenthal's drumming, James Turano as the Big Bopper, and Desmin Borges as Ritchie Valens make up for the loss. --Laura Molzahn a Through 3/11: Wed-Thu 7:30 PM, Fri 8 PM, Sat 5 and 8:30 PM, Sun 3 PM, Mercury Theater, 3745 N.
