This is “Angel of the Morning” that was a hit by Merrilee Rush (birth name Merrilee Gunst) in 1968. The song was written by New York City born songwriter Chip Taylor (birth name James Voight) who is the brother of actor Jon Voight. The song is about a one-night stand.
Merrilee Rush had been playing with bands since the early 1960s. Her band was an opening act for Paul Revere and the Raiders and Mark Lindsay got her in the door to a recording studio where she recorded “Angel…” This was to be her only hit record in spite of the fact that she was nominated for the Grammy for female vocalist of the year in 1968. She still sings around the Seattle area but is now more often occupied with breading Old English Sheepdogs.
“Angel of the Morning” got up to #7 on the Record World singles chart where it remained for 3 weeks (June 30 – July 20, 1968). It did better on the Billboard Hot 100 record charts where it was at #3 for the weeks of June 30 – July 13. The song was recorded by many other artists but was very successful for Juice Newton in 1981.
