Please answer the following question: What is the name of the character forbidden from listening to popular, modern music?  Answer the above question based on the context below:  Mrs Baring, a businesswoman and patron of classical music, has arranged for a celebrated Eastern Bloc musician, Spolenski, to play in a series of concerts in Britain. However, she is aware that she is on the brink of bankruptcy and the Spolenski tour offers a final chance to save her finances. Johnny Burns, an aspiring singer is hanging around a music shop he frequents when he spot Mrs Baring's daughter, Joanna. Enraptured he pretends to be a piano-tuner and goes round to her house to help prepare the piano for a party held in Spolenksi's honour. Later, when Mrs Baring is short of a butler he offers his services and is so successful at his duties that he is taken on in a more permanent basis. He slowly begins to bond and court Joanna while doing his best to conceal his love of popular, modern music from Mrs Baring who is resolutely opposed to it and has forbidden her daughter to listen to it. Her financial problems continue to mount up and her phone is cut due to unpaid bills. Burns' friend and agent, Freddy, meanwhile has secured him an audition with Greenslade, a major popular record label, who are impressed with his performance. Convinced he is going to be a major star, they make plans to sign him up on a long-term contract. Burn's first demand of Greenslade is for money to pay for Mrs Baring's telephone to be restored. Mrs Baring is relieved by this gesture, but  believes the money came from one of her other friends rather than Burns.
