Bollywood meets Swinging London? That will be Purab Aur Pachhim.
I've not seen the movie, but Bossbeat (check out his Bollywood clips for more of the same) put us onto it. The title apparently translates to 'East and West', with the plot revolving around 'a good Indian boy going to swinging London in the 60s'.
Want a clip? Check it out below. No sign of it being available in the UK right now, but I'd guess some specialist sellers will have a copy.
