[6] She wrote the lyrics for "Angel Baby" as a poem for "[her] very first boyfriend" when she was 14 years old, still attending Mission Bay High School in San Diego, California.

[6] According to her personal autobiography she said "I was born Rosalie Hamlin on July 21, 1945 in Klamath Falls, Oregon.

I always enjoyed horseback riding, ice skating, skiing, mountain climbing, fishing and target practicing."

[11] Hamlin along with her band performed six shows with Jackie Wilson at the Brooklyn Paramount Theatre in New York City in late 1960.

[11] When the group formally established a contract, Hamlin found that she was ineligible to collect record royalties from the song because she was not listed as the songwriter.

This led to the group's break-up, and although Hamlin secured the copyright to her music in 1961, decades of battles over royalties followed.

[17] Hamlin formally retired from the music industry in 1963 after her marriage to Originals guitarist Noah Tafolla.

[4][17] In July 2007, a concert honoring Hamlin was held at the Pearson Park Amphitheater in Anaheim, California.
