Butterfield Court in Dudley is where John Bonham lived for a while. John also lived at The Three Men in a Boat pub on Stephenson Avenue, Beechdale, Bloxwich just before he joined Led Zeppelin. The pub landlord was William Bonham, John's uncle. I believe Robert Plant lived there too.
The building featured on the album Led Zeppelin IV is Salisbury Court, Birmingham, not Butterfield Court. The building still stands today.
