What encouraged Robbie Williams to sing?

Los Angeles: Singer Robbie Williams says popular song "Summer Nights", from the movie ‘Grease’, encouraged him to make career in singing.

The popular song was a part of John Travolta and Olivia Newton-John`s 1978 film ‘Grease’, which was an adaptation of 1972 Broadway musical of same name. "My first three years were spent in a pub - and `Summer Nights` was on the jukebox. That was the first record that showed me I had a future in performance - because the punters would put the money in and I`d mime to the record. I`d do the whole bit," thesun.co.uk quoted Williams as saying. The singer is known for songs like "Strong", "Feel", "Misunderstood" and "Candy". IANS
