If he's used to radio and the nursing home has wireless connection, a computer tuned to an internet station would probably be closest to what he's used to. You could just leave the radio station selected and rig a simple on/off for the speakers. There's some comfort in the narration between music even on classical stations, and he may be happier letting them select the music. You wouldn't even necessarily need a laptop. Someone at the church may have an outdated desktop computer that's outdated but is still capable of connecting. It can live under the bed, with only the on/off switch visible.
