In 1971 she released an album titled This is a Recording, an LP of sketches involving her highly popular Ernestine the operator character. It won a Grammy and remains the highest-charting album by a comedienne. She went on to host Saturday Night Live and appear in dozens of successful films including 9 to 5 and Nashville. One of her most acclaimed films was All of Me opposite Steve Martin. In addition to her Grammy award she has won several Emmy and Tony awards and has been nominated for an Academy Award. With such an impressive resume of stage, TV and movie work, it’s easy to see why some people might forget that she is also one of America’s top stand-up comedians. Tomlin performs 8 p.m. Saturday at the Taft Theatre Downtown.
