"Muhammad Shahid Nazir works on a fish stall in Queen’s Market, near to the Olympic Stadium.
More than 1m views on the video sharing site show people love his tune, “come on ladies, come on ladies, one pound fish… Have a have a look, one pound fish.”
He is now in talks with a record label and has also auditioned for the up-coming X factor 2012.
“I feel very good and can’t believe everyone is singing the song,” said Mr Nazir. “It’s become famous.
“People want my autograph and they take photographs as well as make videos of me.”
“West Ham supporters often stop here and tell me they’ve come to hear me sing as well as watch the match.
“Once a head teacher told me that his whole school is singing the one pound fish song.
“I’d been doing the job for just a week before I decided to sing the song which I made up myself. I soon realised it got people’s attention and drew them to the stall to buy fish.”
“My mother prays for me and encourages me to pursue my dream of becoming a singer. Singing has always been my childhood hobby and I want to make a career out of it,” Mr Nazir told BBC.
