“Gracie is in a gay mood as she tells George all about her family and her day at the St Patrick’s Day parade. George is jealous that she is spending too much time with bandleader, Artie Shaw. As he leaves to make some arrangements, Senor Lee arrives with some advice to Gracie about eloping. Artie Shaw plays, Swing Low Sweet Chariot.
George’s plan is to hire an actress to pretend to be his new girlfriend. The hope is to make Gracie jealous and come back to him. Instead, she and Artie get word of the plan and make their own scheme to sabotage George.
They get a homely gal to substitute for the actress. Now it’s a matter of letting George have his pretend fling with the girl. After making George squirm for a while, Gracie ends the show with a song, Let’s Get Away from It All. “
It turns out The Couple Next Door was miserable.
