ПЕРЕВЕДИТЕ ПРИ!!! Life was hard for Noel Gallagher before his success with the group Oasis. He liked school. When he left school, he worked as a builder for his dad. But he and his dad had a good relationship. In the end, he went to work as a builder in another company but he had an accident. After the accident he wrote his first songs. A Manchester band needed a singer but they gave Noel a job helping to carry their guitars and instruments. Theree years later, his younger brother, Liam, asked Noel to join his group as guitarist. Noel said yes, but he wanted to sing their songs. So,he became the band's songwriter. In 2009, after many arguments with his brother he left Oasis. However, Noel started his own band, Noel Gallagher's High Flying Birds, in 2011. In 2013, Noel Gallagher won the lvor Novello award for Outstanding Song Collection
