Listen to the song. It's got steel and walking bass and everything. It is absolutely a country record. I wish I was listening to country radio at the time, but I definitely remember AC WHEN(AM) in Syracuse playing it.I pulled out my Joel Whitburn, and yes they peaked at #37 on 10/5/74 with a song called Fairytale. TBH I never heard of this song. I know Slow Hand, which they recorded, was also a hit for Conway Twitty. But that's it.
Fairytale peaked at #13 on the Hot 100 and #13 on AC charts. But how it charted country is beyond me.
