The 2i's was the inspiration for the establishment of the
Casbah Coffee Club in Liverpool by
Mona Best in the cellar of her family home, which played an important role in the early development of
the Beatles. In 1960,
Bruno Koschmider, manager of the
Kaiserkeller club in Hamburg, visited the 2i's to recruit British rock'n'roll musicians to play at his venue: these included Derry and the Seniors, whose manager
Allan Williams was also the Beatles' first manager, and who also arranged for the latter band to
play in Hamburg for Koschmider. During their time in Hamburg the band worked with Tony Sheridan, who had performed at the 2i's, and later recruited another 2i's veteran,
Jimmie Nicol, to fill in for Ringo Starr on an Australian tour. On 18 September 2006, a
green plaque was unveiled at the site of the 2i's Coffee Bar to commemorate its existence, and to celebrate 50 years of British rock and roll. The coffee bar was immortalised in Wee Willie Harris' song "Rockin’ At The 2i’s", and by Tommy Steele in "Two Eyes", a song recorded for the soundtrack of the film
The Tommy Steele Story. The film also featured a recreation of the coffee bar, albeit much more spacious than in real life, and also featured Tom Littlewood playing a judo instructor.
Ringo Starr mentions "the 2i's Cafe", "That's where Tommy Steele would play", in the song "Rory and the Hurricanes" on his 2015 album
Postcards from Paradise.
Michael Peppiatt mentions the café in his memoir of Francis Bacon: "As a
teenager I'd gone on a rite of passage to the 2i's café to listen to skiffle groups, sipping frothy coffee out of transparent cups and hanging around in the hope of spotting Tommy Steele." ==Resident groups==
