Not to derail this but I think this could be very profound with regards to the evolution of modern cm that I had wondered about . There is a school of thought that much of the gamakas we are used to hearing now are either "added" or "more pronounced" versions of the way CM was even in the very early part of 20th century of later. Even recently, TMK has opined on this a lot (with relation to gamakas in SSP) including a concert where he has sung bhairavi etc. like the olden days - different prayogas, but also minimal gamakas compared to today. He also mentioned that the earlier vintage recordings were indicative of this. I also remember a conversation with vainika of our forum (over a tasty meal at MFAC canteensrkris wrote: V.V.Subramaniam who had accompanied him for long, says Chembai always taught to his disciples at home with complete gamaka laden sangatis but did not himself sing so in concerts. VVS says he doesnt know the reason for this.
TVG says its because he wanted to stick to his own tradition.

I have always wondered if it were so, how did it change (say by 40s?), why, and were there any people who were there in both eras. The above seems to speak that Chembai would be one - who "went with the times" but also "stuck to how he was taught" i.e. as per this immediate older form.
