Input: Question: What artist wrote the song that Vallee begins to sing after Betty wishes her good night? Passage:The film begins at Betty Boop's house, as she throws a house party. She is seen in a room serving a drink to the other animals. Due to the drink, an argument breaks out between two animals, whom ultimately agree at the end to toss a coin. However, when one of the animals flips a coin, it comically ends up sideways. So one of the animals flips again, but flips it so high that a bird comically catches it and takes it. After that, Betty then asks for anyone that can sing and dance. A rabbit then comes forward and says that he can play the piano. So, Betty asks Hanson to bring in the piano. However Hanson is a small bug, so comically has to tug at it to get it in the room, whilst a big hippo comically only carries a stool. Betty then hands the rabbit some sheet music, but the rabbit says that he only plays "by ear". However, when he starts to play, he comically uses his ears to play the piano. Betty then requests for a singer whilst she plays. All of the animals decline her request. Until a picture of Rudy Vallee from a book of sheet music comes to life and says he will sing. Betty then asks Vallee is the songs will be old or new, Vallee then says that he'll sing songs that they will all know; and he'll sing them with the bouncing ball. His first song that he sings is "Deep Night", with footage of beaches and rainforests accompanying the song . The second song that he sings is "A Little Kiss Every Morning", with footage of a painting firstly showcasing multiple species of birds kissing, then transitioning to babies and their mothers, then to young couples, and then to elderly couples. The final song that Vallee sings is "Stein Song", a college song, with accompanying footage showcasing a noisy game of American football. After the three songs, the party concludes, and all the guests depart from Betty's house. Betty then wishes Vallee good night. Vallee, who is in a picture frame, begins to sing "Good Night Sweetheart". After that performance, Betty then laughs and wishes him a good night. The film ends with Vallee singing "Keep a Little Song Handy".
