S Janaki was a part of almost all their albums. During the initial days, RN gave many duets to PBS-SJ. Later their main singers were SPB and S Janaki. Almost all of their songs remain etched as the unforgettable melodies of Kannada Cinema. The romantic duets that came out from the SPB-S Janaki-Rajan-Nagendra combination are considered to be heavenly and evergreen. Radios called the pair of SPB and S Janaki as "Love Birds" and are termed to be the "Best singing pair" in Kannada cinema, owing mainly to their romantic duets composed by Rajan-Nagendra in the 1970s and 80s
