As well as being one half of the comedy duo Stiller And Meara (with his wife Ann) as well as father to Ben, Jerry Stiller was probably best known for playing Frank Costanza on Seinfeld. But to Rush fans, he was a fixture on several tour videos. He would appear in short films that aired as the concert would begin. The R30 Tour was just one of many...here you go.
P.S. - Watch out for the fusili and say hi to Neil.
