S-J were the "house composers" for RK Films and were on their pay-roll till the end. Raj Kapoor used to maintain a music bank where he stored compositions of S-J. Even after the termination of the professional association between Shankar and Raj Kapoor (Jaikishan had died by then), the latter had used a number of S-J's earlier compositions (which were in his custody) for all his films though the credits were given officially to other composers, e.g., Laxmikant-Pyarelal (Bobby, Satyam Shivam Sundaram, Prem Rog) and Ravindra Jain (Ram Teri Ganga Maili). S-J also worked with other stars like Shammi Kapoor, Rajendra Kumar, Dev Anand, Sunil Dutt, Kishore Kumar, Manoj Kumar, Biswajeet, Joy Mukherjee, Dharmendra & Manoj Kumar. Beside them S-J combo worked above all of with Mohammed Rafi and secondly Mukesh, and produced numbers of hits and unmatchable gems. Mohammed Rafi was their favourite singer despite having good reputation with other playback singers of its time.
