Daryl Sherman, Johnny Mercer: A Centennial Tribute (Arbors). So, you think you know all of Johnny Mercer? If you can recite the words to “The Bathtub Ran Over Again” and “Here Come the British,” you probably do. Ms. Sherman also sings Mercer’s lyrics to better-known songs, “Midnight Sun” and “Come Rain or Come Shine” among them. She accompanies herself and plays piano solos, with assistance from Jerry Dodgion, Wycliffe Gordon, Howard Alden, Jay Leonhart and Chuck Redd. Marian McPartland and Barbara Carroll make guest appearances in a collection of 14 Mercer songs splendidly performed.
