Early in my student days at University of California in Berkeley there was a movie theater on Shattuck Ave that booked "art house" type films most nights. But one night a week it booked films made in India (I don't recall the term Bollywood being used much back then). An offering to the many students from India at UCB. I'd attend one of those on occasion. This reminds me so much of what was typical in such films. Always there had to be seemingly unrelated to plot music and dancing.
Later that theater became a porn house.
