This is a hit song from the movie Run starring Madhavan, Meera Jasmine and others directed by Lingusamy and the movie too had done well. The song has been sung by Udit Narayan and Sadhna Sargam. The music for this song has been composed by Vidhyasagar. Comedy actor Vikek had made fun of the Tamil pronunciation of some of these Hindi singers in another movie. In particular he mentions this song and how Udit Narayan pronounces the word Paravaayillai as Parvaa Illai. But the irony is that the word Paravaayillai which is assumed to be a Tamil word is a word which has come from the Hindi phrase Parvah Nahin through Karnataka (Parvahgillaa) to Tamil Nadu and has now become a Tamil Word! Using famous singers from different languages is not wrong. Music is universal and it brings people of different languages, interests, faith or any other difference, together easily!
