Thanks Vkailasam for the SabhApathy cachEri clip. I was too young to watch the movie when it was released

While sequences in later films have very formal concert scenes, this was delightful--guests figured as much as the performers--and the wedded couple--TRR's appreciation of the music and that of the audience was very informal (though some don their hats through the performance!).
Vintage stuff it is, in that it brought back memories of old weddings--sandalwood paste, sprinkling of scented water from pannIr sembu!
As for P.A. Perianayaki--she had an unique voice which appealed to me. Here, I think it's her debut performance. Add to it the stiffness in expression at first and camera consciousness. Soon, they all lighten up and smile. The mrudangam player is an exception. She adds so much liveliness to the scene from the start. Wonder if she continued playing. Turbaned gents, a twelve thirumaN-ed person in the audience, the arrival of VIPs obscuring the stage at the end, were all entertaining to watch.
PAP did have that distinct voice. Years later when I first saw and heard M.S. Sheela, she somehow reminded me of PAP. Another gifted artiste with a unique voice and presence.
The fun part was the request for singing in thamizh and the switch-over!
