The Sensational New Instrumentalist... The Spectaculars
Grand Award G.A. 266 S.D.
Grand Awards was an Enoch Light label. Even though the "Hammond" gets top billing on the album, the music is really a "group" effort.
In typical Light fashion, he credits the jacket illustrator: Elmer Wexler.
Studio musicians, however, aren't credited. I bet there are a few recognizable names to be found in The Spectaculars. Maybe Tony Mottola on guitar? Just a guess.
