But wait! There's more!
(Ganga Jamuna Saraswati, a 1988 Manmohan Desai movie I clearly must see)
I can see it now: it's a quiet morning around the Bachchan family parlor in 1987, and Amitabh wonders out loud, "How should I go about rebuilding my dignity in the public eye after leaving political office in disgrace for corrupt dealings with an arms manufacturer?" 14-year-old Shweta, with a finely honed teenaged taste for sarcasm and finding one's parents hopelessly lame, quips "Well dad, all of my classmates are really into disco and Michael Jackson's Thriller." Add to that a little Manmohan Desai nationalism and taste for pan-India melding, and voilà: "Disco Bhangra" with the must-have accessory of 1983.
Wonderful Katrin has given me much in the time I've known her - pink and yellow Shashi pins, a copy of Teesri Manzil, an invitation to Bavaria - but the news of the existence of "Disco Bhangra" may be the best of all.
