Film Stats & Assorted queries

[Querida]

hey i have two questions:

1. i watched Andha 7 Naatkal yesterday and i am so very sure that i have seen another version of it exactly point for point...it stars Ambika and Bhagayaraj...i don' know if it was a hindi remake or another version in tamil made...and i know it is not Hum Dil De Chuke Sanam which follow the same idea but is not what i am looking for....Can anyone help me?

2. hmmm this is more a language question...in the movie "Thendral" there is this wonderful song sung by Pushpavanam Kuppuswamy...i want to now what the word "thanduvaponae" means in the song please
