"Expresso Bongo" was a movie version of a hit west end musical satire..
and was as 'adult' a movie as the producers could con past the censors
without an X cert..

[the special edition is worth the extra few quid for the directors commentary and a hiariously naff contemporary colour documentary
about soho coffee bars..]


.. and another similar favourite .. though perhaps more beatnik than rock 'n'roll

is "Beat Girl"..

but you probably need to find a bootleg of the uncut widescreen[european export? ]nudey strippers version

shown on Film 4 a few years ago..
