Himesh was very fond of Dard-E-Dil from Karz as a kid which played a kickstart role in his musical career and inspired him as a music director.
This song was composed by Laxmikant-Pyarelal whom Himesh idolizes from da yesteryears bunch of composers.
As a matter of fact, Himesh was supposed to croon a modern re-arranged version of this song (just like Ek Hasina Thi) in his Karzzzz remake but opted against it at da very last minute.
However, he still ended up crooning a short adlip version in da movie itself.
Nevertheless, after completing his tunes for Karzzzz, himesh went to Pyarelal's residence to get his affirmative and got a thumbs up.
Subash Ghai has also praised himesh stating that ""I'm no authority to judge the future work of any talent. Himesh may even prove better, who knows? I know Laxmikant-Pyarelal did a fabulous job in my 'Karz'. But I'm sure Himesh will do a good job. Himesh is today's Laxmikant-Pyarelal. Time brings new people too." - http://www.bollywoodsargam.com/shownews.php?newsstory=708145622
