Big Al: "I once mimed my song to a radio audience in Dusseldorf. Looking back I can't believe they got me to mime on the radio..."

Really? That's wonderful! The things you can do on the radio!

American ventriloquist Edgar Bergen appeared (?) on the radio frequently. As a star turn, he would lipsynch duets with his dummy Charlie McCarthy--WITHOUT MOVING HIS LIPS--in perfect synch, of course.

Marcel Marceau faked his way through John Cage's "4:33," WHILE TUNING HIS CROSS-HANDED AIR CLARINET and no one caught on.

I really did once hear a public radio broadcast of clog-dancing at a folk festival. Allegedly. Maybe it was just people in the studio clomping coconuts on the table.
