from doombuggies:
Of course, the band would really be unimpressive without the fabulous vocal stylings of the "Phantom Five," a collection of singing marble busts. These singing statues (lead by bass vocalist Thurl Ravenscroft [second from left], who is famous for his "Grrrrrrr-REAT!" portrayal of Tony the Tiger) are projected faces on static bust props (in an effect very similar to that of the Madame Leota crystal ball.) Special thanks to Guy Kalicicki for providing the scanned bust cels.
For the record, each filmstrip was labeled on the leader, and each bust is actually a named character. They are, from left: Ned Nub (Jay Meyer), Uncle Theodore (Thurl Ravrenscroft), Rollo Rumkin (Verne Rowe), Phineas Puck (Bob Ebright), and Cousin Al (Chuck Schroeder.)
