I2FS plug: Karthik has posted the Karz/LP find on I2FS and even referenced my post:
A pretty good (read blatant!) find for the day. Laxmikant Pyarelal's Karz theme tune (and consequently the song 'Ek haseena thi' based on that tune) happens to be a direct lift from George Benson's 'We as love' (part of his 1977 album, 'Weekend in LA', written by his keyboard player, Ronnie Foster). Thanks to George Thomas for the info. George has also posted this info in his BlogSpot [Third entry under 'Thursday, May 23, 2002]. Other relevant trivia: Karz, the movie itself was a lift from the 1975 movie 'The Reincarnation of Peter Proud'. Subash Ghai's website talks about this tune too, though, as George adds in his blogspot, they could sure do with a decent proofreader..."The signature tune on the Guitar is still one of the most haunted tunes ever composed in the history of Indian Cinema"!!!
