'Vachaadayyo Saami' makes the right noises.  Set in Rayalaseema, the 'Bharat Ane Nenu' song surely has the right sentimental value going for it.  When it comes to Koratala Siva, local patriotism is the thing.  

Ramajogayya Sastry's lyrics go beyond run-of-the-mill phrases.  'Matti godalu chebutaayi, Seema manushula kashtalu' take the cake.  The theme of saving the poverty-stricken village ('Aa kanna thalli kanti neeru thudichina rojegaa') is also conveyed in heartfelt language.  

Rendered to a booming effect by Kailash Kher and Divya Kumar (their voices are playful yet they induce earnestness in the listener), the song has Devi Sri Prasad noticeably getting into a 'Vandemataram' Srinivas mode.  (This happened with Rangasthalam's 'Aa Gattununtaava' song as well).  

Keyboards by Vikas Badisa, Rhythm by Kalyan, Cello by Shekhar, and Shehnai by Balesh are nimble.
