Tickets for a preview performance of Broadway’s endlessly delayed, accident-riddled, critically savaged, ever-changing Spider-Man: Turn Off the Dark are still going for upwards of $275. But Late Show viewers got a free peek at the show last night, when cast members Reeve Carney (Peter Parker/Spider-Man), T.V. Carpio (the villainess Arachne), and Jennifer Damiano (Mary Jane) stopped by Letterman’s set to sing “Rise Above,” one of the numbers penned for the show by U2’s Bono and the Edge. Taken out of its context from the story — the song comes right after the death of Peter’s beloved Uncle Ben — the performance came off as a strangely angsty advertisement for the musical, whose TV ads have mostly spotlighted high-stakes acrobatics and surreal set pieces. Check out the clip below, and then let us know: Does it make you want to see the musical?
