Noticed recently that Music Director PREETAM who has given music to some big hits recently (Dhoom, Garam Masala, Chocolate etc) carries last name CHAKRABORTY.

Is Preetam Chakraborty related to old time music directors Sapan Chakraborty or to Sapan Jagmohan ?? Could 'Sapan Jagmohan' be 'Sapan Chapraborty ---- Jagmohan duo' ??

BTW, imdb.com doesn't have many films credited to Sapan Chakraborty for music direction (most entries are for assistant to music directors), but am sure there are many 'B' & 'C' grade films for which Sapan Chakraborty was the main Music Director. Do you recall any such films ??
