I think it was originally sung by Noor Jehan in the late 70`s.. but you shouldn`t have any difficulty finding it since there have been loads of remixes

Rani Randip sings it and it`s also been on the XLNC album

The name of the song is Kite .. Ghudi means Kite in English.

Guddi Wangu Ajj Minu Sajjna
Udhai Ja Udhai Ja Udhai Ja

Just like a kite, my love
Fly me higher and higher

(I know it sounds lame in English)

Hope that helped : )
