230 Oak Grove Street. This hotel was (and is) by Loring Park in Minneapolis – now apartments. It was built in 1920, and was one of the most posh hotels in town, hosting the likes of Elizabeth Taylor and Jackie Gleason when they were in town. In 1923 it was the home of radio station WLAG, which became WCCO. Presumably it had a house and/or radio orchestra.

Alan Freed found this postcard of the Oak Grove Hotel from the 1950s.
