I told you yesterday (and Page Six must have read it) that “Spider Man: Turn off the Dark” stars Reeve Carney and Jennifer Damiano are a couple in real life, too. Well, why not? As I said yesterday, these “Spider Man” actors have been stuck together like lab rats for a year. During the spring, they rehearsed one show for three hours a day and then performed another at night. Romance has infected the cast like the poison spider that bites Peter Parker. Also a couple are the principal understudies–I’m told Matthew James Thomas, who alternates for Carney, and Kristen Martin, who understudies Damiano, are hooked up. Meantime, the “Turn off the Dark” soundtrack has hit amazon, and it’s pretty interesting. Bono and The Edge perform the very Wh0-like song, “Picture This,” with Carney and Damiano on secondary vocals. Same for Bono and Edge on an alternate version of “Rise Above.” Edge also is featured playing guitat on “Sinisterio,” although it seems to have to the old lyrics–“set yourself on fire” has been reworded in the actual show so as not to inspire self-immolation. P.S. Another column got this wrong: T.V. Carpio, who plays Arachne, did make it into Bono’s private party-within-a-private-party- within- a- party on opening night. She only went outside the big blue curtain to say hello to friends who weren’t allowed in.
