Connie Francis was talked into recording “Who’s Sorry Now”
by her father who was adamant that it would be a rock and
roll smash hit. Francis didn’t want to record the song at
first, but used leftover studio time to make the recording
with just two takes as a goodwill gesture to her father. It
rose as high as #4 on the Billboard Hot 100 in the spring
of 1958.

Connie will turn 74 in December
