We've put the best bits of Comic Relief music and comedy all in one place - in the Comic Relief room on iTunes. Behold a treasure trove of exciting and exclusive content, including Comic Relief singles through the ages, music videos, podcasts, audiobooks and celebrity playlists.

This year there are two Comic Relief singles: "Walk This Way" by Sugababes vs Girls Aloud, and a special surprise from Peter Kay, to be released during the Comic Relief TV show on March 16th. Net profits from both singles go to Comic Relief.
