The Cavern Club

The Cavern Club was a nightclub in Liverpool where the Beatles made their debut performance in 1961. According to the Eleventh Doctor, 96% of the audience were time travellers. (COMIC: What He Wants...)

By one account, the group briefly turned into a pack of howling wolves during the performance, as a result of Rose-the-cat meddling with the Doctor's TARDIS. (COMIC: A Rose by Any Other Name)

Graham O'Brien asked the Thirteenth Doctor if she could take him there to see the group. The Doctor declined, claiming to have "used up all the dates". (COMIC: The Power of the Mobox)
