Picking up on this now, as I just viewed it.
Elsewhere, I commented on how members seemed to be unaware
of Jesudas singing Salil Chowdhury's Malayalam numbers.
Members of this thread are probably aware of MSV's collaboration
with T.K. Ramamurthy, but surprisingly no one commented on this.
The duo split in 1965 ( think they started in the early '50s ).
As with most famous duos ( read The Beatles, The Supremes,
our own Shankar Jaikishan ), when they split or one of them
passes on, the quality of the music of the solo member/s
tends to be less than the quality of the collaborative effort.
You do see gems here and there, but when the collaboration
was in effect, you could see gems EVERYWHERE !!
