A UK tour of occurred during May and June 1969 culminating in the show dubbed "The Final Lunacy" at Royal Albert Hall on 26 June 1969. Considered one of the most experimental concerts by Pink Floyd, it featured a crew member dressed as a gorilla, a cannon that fired, and band members sawing wood on the stage. At the finale of "The Journey" suite the band was joined on stage by the brass section of the Royal Philharmonic Orchestra and the ladies of the Ealing Central Amateur Choir, and at the very end a huge pink smoke bomb was let off.
