(the first clip was wrong, from a 1982 annie that was good but not the original people rave about)
Annie is a Broadway musical based upon the popular Harold Gray comic strip Little Orphan Annie, with music by Charles Strouse, lyrics by Martin Charnin, and the book by Thomas Meehan. The original Broadway production opened in 1977. It ran for 6 years on Broadway. (Catz ran for 18 - I never saw it)
That (phenominal) original Broadway production opened at the Alvin Theatre on April 21, 1977 and starred Andrea McArdle as Annie
