Kiss the Boys Goodbye Dance
From Tardis Wiki, the free Doctor Who reference
The Kiss the Boys Goodbye Dance took place at The Ritz, Cardiff in 1941.
When the Cardiff Space-Time Rift took them back in time, Toshiko Sato and Jack Harkness attended the dance. Toshiko danced with George for a while but when Jack pulled them apart he reacted violently and the two fought. They were seperated by the real Jack Harkness. (TW: Captain Jack Harkness)
