Multi-instrumentalist Peter Pringle shared this music video for his theremin arrangement of God Only Knows. 

He also shared some background on the Beach Boys and the theremin used in his cover:

Here’s a bit of theremin trivia. Back in the 1950’s the Wilson family (aka The Beach Boys) were friends of the Hoffman family, and occasionally when the Wilsons visited the Hoffmans, the boys would get a chance to play the 1929 RCA theremin that belonged to Hollywood thereminist, Samuel Hoffman. That is the same theremin that you hear in this video and that is how The Beach Boys became acquainted with the instrument.

This song – GOD ONLY KNOWS – was written by Beach Boy, Brian Wilson, and was recorded by the group in 1966.
