1950s US Rockabilly artist. He had a short lived career releasing his single 'Trapped Love / Steelworker Blues' in 1958 on the local Val label. The record sold well and was picked up for national release by Dot Records. 'Trapped Love' was later covered by The Cramps. Doing a little research into Keith Courvale, it MAY be that Keith Courvale was actually a pseudonym for one Keith Allyn Poulin as shown in "Catalog of Copyright Entries: Third Series." In it, it shows Keith Courvale as having that pseudonym and who obtained a copyright in April, 1960 for a song titled, "High School Hop." I have NOT been able to verify if one and the same.
