3 songs actually that I have always loved since my childhood... :)
1, Jahan dhal dhal par sone ki chidiya - Mohd Rafi and others from the film Sikander E Azam
2, Ab watan azad hai - again Rafi for the film Mujhe jeene do
and
3, Jaanewale sipahi se poocho woh kahan - Manna dey for the film Usne Kaha Tha ...
I can add a dozen more since there are many beautiful songs on patriotism...
Oh I too love the song jahan daal daal pe :) ..and my other favorites are mere desh ki dharti and vande amtaram :) :)
Jahan daal daal pe is my favoruite too, only I always thought it was from movie Amrapali! Another favorite of mine is Kar Chale Hum Fida Jaan - o- Tan Sathiyo...
Actually I should have included that as well since it is one of the most touching songs, the lyrics are great ! have you seen the film Haqeeqat , Kalyani ? This song has been very effectively picturised,left me in tears when I watched it the first time...The film itself is a master piece !
