One of the most successful girl-groups of the 1950s and 1960s was the Shirelles with classic hits like “Soldier Boy, “Dedicated to the One I Love,” and “Mama Said (There’d Be Days Like This.)” It all started in 1957 with “I Met Him On a Sunday.” Find a copy of the 45 on Decca Records (1958) and $25.00 could be yours.
