The getup in New Yorks get-up-and-go comes from the switchboard operators of Susanswerphone. Need a wake-up call? Your appointments? Encouragement from Mom? A racetrack bet? It all comes from that dutiful nerve - or noive - center that keeps enterprises enterprising and, maybe, wedding bells ringing. Judy Holliday reprises her Tony -winning Broadway role of irrepressible switchboard girl Ella in a jubilant adaptation that marked her final movie and the final teaming of movie-musical titans Arthur Freed and Vincente Minnelli. Dean Martin costars as a struggling playwright in for a surprise when he learns Moms identity. The sparkling Jule Styne/Betty Comden/Adolph Green score includes Hollidays heartfelt The Partys Over and the jolly Holliday/Martin duet Just in Time. You've dialed the right number, musical fans!
