Letterman helps Madonna ride again

Madonna got back on the horse again - with assistance from David Letterman. The talk-show host and Madonna rode along 53rd St in Manhattan on the Late Show, the singer's first ride since being thrown from a horse in England.

Letterman, a novice rider, traded stories about tumbles. Madonna said she hadn't been back on a horse since her fall "because my record company is not very keen on the idea of me injuring myself"'.
