From Wikipedia, et.al.:
Come Blow Your Horn was Neil Simon's first play, which premiered in the United States in 1961 and had
a London production in 1962 at the Prince of Wales Theatre.
The play follows Alan and Buddy Baker, brothers who have decided to leave their family's waxed-fruit
business and experience the good life. In the beginning of the play, Alan is a typical ladies' man,
and his younger brother is a 21-year-old virgin. As the play progresses falls in love with Connie,
one of the girls that he is sleeping with, and when she leaves his life, he falls apart. While Alan
mourns the loss of Connie, Buddy becomes a ladies' man himself.
An offstage character in the play is Felix Ungar, later one of the protagonists of Simon's The Odd
The show is enjoyable, if a little long in parts, and Simon writes in a quick, breezy style. It won't
make you think too hard, and it won't change your life, but it will certainly make you laugh. It's a
fun show, and that's what really matters.
The play was made into a film in 1963.
