When 16-year-old Shapiro played the first engagement of her British nationwide tour in February 1963, The Beatles were second-billed to her act.
Her recording "Walking Back To Happiness" appeared on Billboard's "Hot
100" pop music chart for one week at #100 (last place), 4 December
1961. She never appeared again on any of Billboard's USA music charts,
a unique achievement for a solo artist.
She is best known for her two 1961 UK chart toppers, "You Don't Know" and "Walkin' Back to Happiness", both recorded when she was just fourteen years old.
