Welcome to SOTW. That Weidoeft style was VERY popular in the 1920's. There is a recording of a guy named "Stump" (or was it "Stomp", I've seen it both ways) Evans who played alto saxophone in Jelly Roll Morton's Red Hot Peppers (circa 1926 or so), who played like that video clip you attached. The tune was WILD MAN BLUES, if you want to research it.
Then, there was All Gallodoro (did I get that spelling correct?) who had great technique similar to Weidoeft . . . and Jimmy Dorsey came pretty close. Bunches of players did that. Don't know how they trained for it, though. A current player, Ted Hegvic (another misspelling, I'm sure) has issued albums doing that technique. DAVE
