After lending her voice to two successful songs this year - Joganiyan for Tevar and Sannata for Shamitabh, Shruti Haasan has finally lent her voice to a song picturized on her for her film Gabbar. What's more incredible is that this talented actress - musician recorded the song in one hour flat without any breaks!

A source said, "Shruti was shooting in the village of Pollachi for one of her films. This is one of 6 films of Shruti's line up that releases this year. Amidst her films schedules and her numerous brand shoots, she had just half a day to complete this recording. After a 2 hour car ride to Coimbatore and then a flight to Mumbai, Shruti landed and went straight into the recording studio. She had prepped the song in advance and had worked on the voicing so that she can maximize her output at the studio and thats exactly what happened. The music director got what he wanted from her for the entire song within an hour post which she took a flight back to resume her shoot in Pollachi. "
