Except "padi parandha", the other songs are delightful melodies. "Thanga changili" has that "drop dead" kind of interludes . I had difficulty differentiating between "keeravani" and "kapi" in film songs. I remember the gruelling rehearsals we underwent , to achieve the vocal counterpoint harmony for "keeravani iravile nilavile". "MalargaLile aaradhanai" from "karumbu vil" and "kajuraho kanavile" of recent times are also in my favourite "keeravani" list.
Keeravani was Raja's pet scale for a long time until Vidhayasagar usurped it for "anbe anbe","thithikudhe","aasai aasai"."thavamindri kidaitha varame","kadhal vandhadhum" etc. But what baffles me to no end is why I have not heard much of keeravani from the MD by that name whiile I have heard many hindhoLam,sudhadhanyasi,aabheri flavour from him
