John Mayer took the stage last night at London's Hammersmith Apollo for his latest show in England, and he managed to keep the dirty jokes to a minimum, unlike his performance last week at the city's Hard Rock Cafe.

He recorded a segment for Larry King's Haiti telethon, which aired last night with cameos from Nicole Richie, Jennifer Lopez, and more.
