The very fact that Diana Ross' third album was Diana! The Original TV Soundtrack and not a full-fledged studio record was ample proof that she was more concerned with being an all-around entertainer than simply a singer. Fortunately, she was very good as an entertainer, as Diana! illustrates. True, a few moments -- namely the Bill Cosby and Danny Thomas sequences and her duets with the comedians -- fall flat without visuals, but her showtunes and covers are all quite enjoyable. Nevertheless, they can't help but be overshadowed by the Jackson 5's medley, which captures the group at their dynamic prime. Even if Diana is eclipsed on Diana!, the best moments on the record prove that she is a fine showwoman in her own right.
