Kevin, Nick, and Joe Jonas made an appearance on The Late Show with David Letterman this week. They will also be appearing on this week’s Saturday Night Live (SNL) with host Alec Baldwin.

I saw The Jonas Brothers perform with Stevie Wonder at the Grammys and wasn’t too impressed. Joe sounded like his voice was cracking, and Nick forgot some of the words. Was their Letterman performance any better?

More new pics of the Jonas Brothers in NYC after the jump.
