Task: Question Answering
Input (English): Passage: Audrey Alston encouraged Britten to go to symphony concerts in Norwich. At one of these, during the triennial Norfolk and Norwich Festival in October 1924,  he heard Frank Bridge's orchestral poem The Sea, conducted by the composer. It was the first substantial piece of modern music he had ever encountered, and he was, in his own phrase, "knocked sideways" by it. Audrey Alston was a friend of Bridge; when he returned to Norwich for the next festival in 1927 she brought her not quite 14-year-old pupil to meet him. Bridge was impressed with the boy, and after they had gone through some of Britten's compositions together he invited him to come to London to take lessons from him. Robert Britten, supported by Thomas Sewell, doubted the wisdom of pursuing a composing career; a compromise was agreed by which Britten would, as planned, go on to his public school the following year but would make regular day-trips to London to study composition with Bridge and piano with his colleague Harold Samuel.Bridge impressed on Britten the importance of scrupulous attention to the technical craft of composing and the maxim that "you should find yourself and be true to what you found." The earliest substantial works Britten composed while studying with Bridge are the String Quartet in F, completed in April 1928, and the Quatre Chansons Françaises, a song-cycle for high voice and orchestra. Authorities differ on the extent of Bridge's influence on his pupil's technique. Humphrey Carpenter and Michael Oliver judge that Britten's abilities as an orchestrator were essentially self-taught; Donald Mitchell considers that Bridge had an important influence on the cycle. 
Question: What is the first name of the person who was friends with Alston when he returned to Norwich?
Output (English): Bridge.
