I do not class Afternoon as country & western (no matter what the others may call it; no pickup trucks, no dogs, no twangy banjos, etc!), more like mild folk rock; whatever, the song did chart and did quite well. Even I liked the catchy tune and words.
From Wikipedia:
""Afternoon Delight" is a song recorded by Starland Vocal Band. It was written by band member Bill Danoff. In the US, it became a #1 single on July 10, 1976 and earned a gold record.".
Note that it took me 43 years to finally buy the single! 🤔
