Prem Pujari
This wouldn't have found mention in Dev Anand's top 10 list if it didn't have the song by lyricist Neeraj. Phoolon ke rang se, dil ki kalam se is one of the most beautiful, romantic Hindi songs ever written. And the credit for this goes to S D Burman too.
Lata Mangeshkar's Rangeela re is another big draw of this patriotic film about a spy, played by Dev.
