Lyin Eyes s a song written by Don Henley and Glenn Frey with Frey singing lead vocals. It was the second single from their One of These Nights album, reaching #2 on the Billboard Hot 100 chart 

The record also received a Grammy  for Best Pop Performance by a Group, and was also nominated for Record of the Year. The single version of the song is shortened quite a bit from the album version, removing the entire second verse, the second chorus and four lines in the middle of the third verse. Top 40 Radio in 1975 didn't usually play songs longer than 4 minutes so the run time on the 45 rpm label was listed as 3:58, but the actual playing time was 4:14.

During the Eagles 2009 concert tour, Glenn Frey talked about the origin for the song stating that he and Don Henley frequented an LA restaurant/bar, Dan Tana's, where the most beautiful of beautiful women frequented. They witnessed a meeting between a man and a woman and made up a scenario of secret love and that's how the song arose.
