Barbara Streisand was a recent guest on the Tonight Show - first time on late-nite TV in decades.

Jimmy Fallon asked her why she hadn't toured for such a long time.

She gave a concert in Central Park; 150,000 in attendance, and forgot the lyrics to 3 of her songs on her set list.

She didn't tour for 27 years after that!

BTW, Fallon did a great job singing some classics with her.
