Webster Booth sings "Be Thou Faithful unto Death" from "St Paul" by Mendelssohn. He is accompanied by the Hallé Orchestra, conducted by Warwick Braithwaite. The recording was made on 28 August 1942. HMV C3309. The same recording is also on YouTube, but I have managed to make a cleaner recording here.
