Here's an early 80s Kalyanji Anandji score featuring a couple of really good songs. The poppy, sitar-driven 'Sathiya Re' is almost a cousin to 'Apradh's 'Ae Naujawan Hai Sub Kuchh Yahan'; possibly not as funky but equally compelling; and 'Pardes Men Jake To' manages to be infectious without having a very strong melody, boosted by jazzy interludes and neat keyboard (Clavioline?) riffs.
From what I've read, 'Kashish' is another film about traditional Indian values being corrupted by dubious Western activities; drinking, drug taking, dancing, pre-marital sex. The instrumental 'Music Theme' apparently serves as background music for a drug scene; typically it's wonderful and I wish it was on YouTube.
