I had a similar experience when I converted an old album from Night (who had a hit song called "Hot Summer Nights" in 1979). Not only did iTunes supply me with album art and metadata tags but they suggested that I go back to my attic and convert John Stewart's "Bombs Away Dream Babies" to MP3 as well.
Stewart, a polished songwriter and musician, spent many days on the road playing at NCO and Officer Clubs overseas.
