I keep thinking that The Mills Brothers are easily enough ignored, but putting that thought into action seems to run into a snag every few years, and, as in these two cases, in some pretty spectacularly unlikely places.
The Basie thing is not really surprising, just the song itself, and hearing that LOL moment when Jaws just ignores the changes at the end of his solo to throw in that one lick, Lockjaw Davis don't give a damn about no Glen Campbell or no John Hartford, Lockjaw Davis = Lockjaw Davis, so BOOM, that what you get for your money, that's what you came to hear, right?, but the Welk clip is priceless at many levels & almost up there with the Johnny Hodges album as example of an America that could have existed but didn't, because the only way that it could have existed was for the real America to have never existed, but hey, that's the thing that makes the show business, right?
And really, didn't the Mills Brothers always swing? Even if/after it became a formula?
