One of the very well researched works.
More intersting is very orginal selction of subjects.
On personal note, good many of songs selected for any particular post has my personal favorites too.
I have located the Audio CD ‘Alaap – Classical Legends in Hindi Films [CDF 124064], in which Sa Re Ga Ma have released hindi film songs rendered by the classical singers. The two songs by Shobha Gurtu – ‘बंधन बांधो ‘ from पाकीझा and ‘सैयां रूठ गये’ from मैं तुलसी तेरे आंगन की – are indeed the real collectors’ gems, as these are not available elasehwere.
