Yes same title .I did not know that but now you've told me I'm not surprised. Never saw the film of The ChoirBoys but read the book a very long time ago, it is brilliant. The only book I've ever read and then re-read immediately. The author Joseph Wambaugh is a retired LA cop. He wrote loads of fiction and non fiction about the police in USA . Hilarious and heart-breaking in equal measures. Well worth looking him up if you haven't read any of his books. there's one called The Onion Field that is exceptional - non fiction about the kidnapping of two LAPD officers and the subsequent murder of one of them. I think that was made into a film too.
