Billy Boy & Mary Lou was released in June 1977 on
MCA Records.
Billy Boy & Mary Lou was Turner's final chart appearance on the latter chart. The album included two singles released between 1977 and 1978. The first single, "Where Are You Going Billy Boy", was released in June 1977. Spending 12 weeks on the
Billboard Hot Country Singles chart, it reached a peak position of 18 on the latter chart. The single also climbed to number 22 on the Canadian
RPM Country Singles chart. A second single was released to radio in January 1978. The single also became a top 40 hit on the
RPM Country Singles chart, reaching number 30. The album received a negative review from
Allmusic, receiving only two stars. Critic Eugene Chadbourne commented that the songwriting quality was low. Chadbourne highlighted the track, "Country Lay on Mind", in his review. "'Country Lay on My Mind' is not just an example of a substandard theme in country songwriting (i.e., songs about just how darn country the artist is). It drags in sexual metaphors and it is hard to believe these performers weren't aware of what they would wind up with -- take another look at the title to get the point," he commented. ==Track listing==
