[1] In the November 17, 1979 issue, Billboard's review said, "This is the popular country duo's tenth anniversary of making records together.

With a selection of contemporary and standard songs, the duo score with Randy Goodrum's "True Love" and Mac Davis' "Baby Don't Get Hooked On Me".

Also contained is a rousing version of "Hit the Road Jack" and Hank Cochran's "That's All That Matters".

The songs are all well selected and balanced showing the duo stretching out from their traditional hard country sound.
