From our steel guitar roots.......Found this on youtube.
Sol Hoopii and Bud Tutmarc Play Three Gospel Songs in One on their Hawaiian Steel Guitars recorded 1953. They play Aloha Oe (He's Coming Soon), Mansion over the Hilltop and It is No Secret all at the same time. Marv Strum on rhythm guitar, Roland Tabell on piano.

Chuck: I think your post and the latest Clip Of The Week by Walter Stettner show the actual tonal and tuning developement of the steel guitar. You can hear the styling changes brought about by improved amplifiers as well as the introduction of the 6th tuning by Jerry Byrd. Which is another reason I think the COTW is Kayton because he has always paid his dues to Jerry's influence on all of us.
