The next job he had was at Leeds Parish Church. This was the only job he had in his life which was not at a cathedral, but his choir at Leeds was probably better than any of the cathedral choirs he had. The services there were very good, and he improved the choir singing. Leeds was not a nice town in those days. It was very badly polluted through industry. Wesley earned extra money by giving music lessons. He was also in demand for giving organ recitals in different churches. He gave the choir more modern music to sing, including his own compositions. He wrote an introduction to a book of psalm tunes in which he criticized the state of the church in England. He did it in a very personal way and it made his employers angry.
