One of my favorite impressionists is a gent named Bob Anderson, who's been delighting audiences in Vegas and Branson for many decades. He's a pretty good singer when he's not doing impressions but he also has this amazing repertoire of mimicry. Basically, he does every male vocalist who ever headlined in Vegas including some pretty obscure ones. Last time I saw him, he did Frank, Dino, Tony and Sammy but he also did Mel Tormé, Otis Redding and Jack Jones.
Here he is on the 1979 Jerry Lewis Telethon. He opens as himself, then becomes Tony Bennett, Dean Martin and Tom Jones in that order. Jerry's reactions to the middle impression are priceless.
Anderson can currently be found at the Palazzo hotel-casino in Vegas starring in a Frank Sinatra tribute with a 32 piece orchestra. Having a 32 piece orchestra in that town in the era of (mostly) pre-recorded music is almost as impressive as any performer, Frank included, who might be singing to their music. But I'll bet you Bob is real good…
