When the Cat is away the Mice are at Play! Farhan Akhtar did just that last night when he and his friend Vir Das were out crashing party after party on a wild night out running through several pubs in Mumbai. And all this while Vidya Balan was away!

Well! To put it in perspective; they were essentially recreating the eternal bachelor song "Harrys not a Brahmachari" from their film ‘Shaadi Ke Side/Effects’ in which they crash parties, weddings and what not.

Guess Men always turn into Bachelors' when the wife is away!"

According to Producer Pritish Nandy, "Harry's Not A Brahmachari" is that situation that every man, specially married men, would love to be a part of. It's wicked, it's fun and it's crazy! Most importantly, it shows every man how to have a fabulous time minus and despite the Mrs!

Interestingly the album of the film has a song for every situation and phase of life. "Harry's Not A Brahmachari" is the singlehood/bachelor phase. Next up for release is the love and proposal song, the wedding blues song follows and then understandably one hits the apology phase and finally even a lullaby!

The much awaited music of ‘Shaadi Ke Side/Effects’, composed by Pritam and on Bhushan Kumar's T-Series, recently its first single - "Harry's Not A Brahmachari" and it is turning out to be catching on quickly among youngsters through online medium! Said Balaji CEO, Alpana Mishra, "Digital till recently called the future; has quickly become the present. People now prefer watching the song online rather than waiting for it to come on television. Farhan and Vir introduced first the audio and then the video of the song to the media and audience last night.

Produced by Balaji Motion Pictures and Pritish Nandy Communications and Directed by Saket Chaudhary ‘Shaadi Ke Side/Effects’ releases on February 28.
