Hi! I read this before but I enjoyed reading it again today after a long time: http://musicmavericks.blogspot.com/2006/06/of-arr-and-hindustani.html
Some interesting info on "Sona Nahi Na Sahi" and one interlude of "Radha Kaise
Na Jale". Radha Kaise Na Jale is in Bheempalasi but the 2nd interlude has a
very mild but clever deviation. I could sense it when i heard it the first
time, but couldnt pinpoint the raaga.
Regards
Aakarsh
