Brown note?
A slightly off-topic aside re: Wannamaker organ - about 10 years ago my church had just installed a new pipe organ. There was a local kid of about 16 who was supposedly a prodigy, though I was dubious of the claim. Arrangements were made for him to perform a recital on our new instrument, and being a recording engineer I decided to do my thing. I should say I was on the committee that spec'd and purchased the organ and I'm also a professional vocalist and had been on staff as the soloist in this church for years, so I was intimately familiar with the instrument and the space. So I set up my microphones and the kid shows up with his manager, who immediately tells me I'm doing it wrong and I shouldn't have that mic there. I tell him to trust me and ignore him. The kid plays his recital and it's actually fantastic. He lived up to the hype. I send him a CD of my recording and he gets back to me a couple days later saying "Thank you so much - I've never had a really good recording of one of my performances!" He used the recording in his application to the Curtis Institute of Music in Philadelphia, was admitted early, and got a job playing the organ at Wannamaker's several times a week. So if you heard that organ 5 years ago or so, he was likely the one playing it.
