JD Sumner's Lowest CHEST Notes With Each Group He Sang With (except Elvis recordings)

Here's a compilation of low notes in CHEST voice that JD sang through the years with the different quartets he sang with. He really was the lowest bass singer on earth and will still be the lowest for a long time.
I didn't include the recordings during Elvis' concerts because there are too many. If you want to see a lot of low notes with Elvis you can watch this video :    • JD Sumner Extreme Low Notes Compilati...

The Eb1 at 9:58 is a F1
at 16:10 he actually touches a B0-C1 very briefly
