25 O'Clock is an EP which was the first release of The Dukes of Stratosphear (a side project of the members of XTC), and was also the title song from that release. Joined by XTC member Dave Gregory's brother Ian Gregory on drums, the Dukes indulged in the stylistic tropes of 1960s psychedelia, particularly the British variety. The band issued a single and made a promotional film for "The Mole from the Ministry" (a song that owes a great deal to The Beatles' "I Am the Walrus").
