However, their vocal efforts weren't up to scratch on theme tune 'On Me Ead', penned by Lily's dad Keith Allen. It was then the 'Smile' hitmaker made her secret pop debut as a fresh-faced 14-year-old. “When the Mike Bassett soundtrack was put together, the deadlines were really tight," the Sun quoted a source as saying.
“The producers didn't have time to spend a week in the studio getting the girls' vocals sorted, plus Natasha never turned up because she was ill, so there was a panic. Luckily, Keith Allen wrote the song and happened to bring Lily along to a lot of the studio sessions."
“Keith said to give her a try because he thought she had a good voice. Sure enough, everyone was astounded by how good she was. It only took her half a day to nail it. Liz and Jenny are on the finished song but Lily was the third member, with the strongest vocal, patching the whole thing up," the source added.
