MUMBAI: Singers Shaan and KK have once again teamed up to sing the title track `Sabko Khuda Hafij Hum To Ho Gaye Rafoo Chakkar` for the upcoming film, Rafoo Chakkar - Fun on the Run. The song has been composed by Siddharth and Suhas, penned by Irfan and was recorded at the Josva Studios. The duo`s only duet was `Dus Bahane Kar Ke Le Gaye Dil` for the movie Dus, which was a huge hit. Director B H Tharun Kumar shared, "The chemistry shared by both Shaan and KK was great in the movie Dus. Their voices jelled perfectly and could match each other`s sur to sur and taal to taal. We needed something really peppy and foot tapping as the title track and could not think of anybody else but Shaan and KK. They have done a fantastic job.
