Hardly goes by a day when I haven't thanked the musicians/composers, lyricists and singers of Golden Era of Bollywood Music (roughly 1955 through 1975). I re-iterate, these have made my life a little more enjoyable, few minutes at a time!
I am disappointed that I was not born in their era (physically, that is, because many believe I mentally still am!), but then, I'm thankful that, at the least, I am born in an era when it is still possible to have access to some/most of their masterful work!
By no means a complete list, but fairly representative, are:
O.P. Nayyar, Madan Mohan, R.D. Burman, S.D. Burman, Shankar-Jaikishan, Ravindra Jain, Laxmikant-Pyarelal and Kalyanji-Anandji.
Sahir Ludhianvi, Ravindra Jain, Kaifi Azmi, Shakeel Badayuni, Majrooh Sultanpuri, Shailendra.
Mohammad Rafi, Mukesh, Talat Mahmood, Manna Dey, Asha Bhosle, Geeta Dutt, Lata Mangeshkar, Kishore Kumar.
p.s.: Don't focus on the video, it ain't that great. Just take in the song sans video.
