Song and dance It's still a singular sensation:

A Chorus Line

is legendary, a winner of a Pulitzer Prize, a Tony Award and owner of a 15-year Broadway run. The dance musical goes on at 1 p.m. today at

the Forrest Theatre

Call 1-800-447-7400. . . . If Jerome Kern only wrote "The Way You Look Tonight," Harold Arlen just "Stormy Weather," and George Gershwin "Someone to Watch Over Me," they would still have secured their places in the popular-music canon - but the three prolific composers did much more, of course, as that's the basis for

American Songbook
