Now this may help tickle your dancing pants at this time of day with a distinct dampness hurtling around the house here . . . . 
Now I didn't buy this when it came out but as is the case with some other singles here, I found in the bargain bins (contrary to what it must seem like that I must have bought EVERYTHING when it came out) it was an ex-jukebox single  but the music haunted me as so often was the case with Paul Simon and he still can . . . . . . . 
If this doesn't get you dancing around the living room in your pants then there is something wrong with your bones! . . . . . . . [and your pants]

On this day in music history: August 6, 1980 - “Late In The Evening” by Paul Simon is released. Written by Paul Simon, it is the sixteenth solo single for the singer, songwriter and musician from Queens, NY. The latin flavored “Late In The Evening”, is issued as the first single from the soundtrack to his first starring role in the film “One Trick Pony”. The plot (based on both true life experiences and dramatic fictionalization) centers around Simon, portraying a once popular musician on the down side of his career, looking to make a comeback. The song and soundtrack album features instrumental backing by the Jazz/Funk band Stuff. The film and the accompanying soundtrack album actually feature different versions of the same material. “Late In The Evening” features musicians Steve Gadd (drums), Eric Gale, Hiram Bullock (guitars), Tony Levin (bass), Richard Tee (keyboards), Ralph MacDonald (percussion), Michael Brecker, David Sanborn (saxophones), Jon Faddis (flugelhorn), Randy Brecker, Marvin Stamm (trumpets), Patti Austin and Lani Groves (background vocals). “Late In The Evening” peaks at #6 on the Billboard Hot 100 on September 27, 1980, and also receiving a Grammy Nomination for Best Pop Vocal Performance, Male in 1981.
