Cleveland, late 1950s
Don Hart was 25 when he decided to give rock and roll a try. His real name was Don O'Sickey. He had graduated from John Adams HS and joined the Army where he was a DJ. After his service was finished, he had a couple short lived DJ jobs before returning to Cleveland. He recorded one 45 for Reserve.
After the 45, he was reported as starting a record label called Delightful records. Although a couple 45s were announced, with the titles "Girl Of My Life" and "I'm Not Ready Now", these don't seem to have been released.
The Cleveland Don Hart does not appear to be same as another Don Hart who recorded for Roulette,
