"I've Got You Under My Skin" is episode 14 of season 1 in the television show Angel. Just as Cordelia succeeds at opening Angel up about Doyle and the events surrounding his death, she suffers a vision about an ancient Ethros demon, which turns out to have been possessing the Anderson's son, Ryan, for years. Angel, Wesley and Cordelia perform an exorcism that expels the demon from the child, but it escapes the trap they set and roams free to possess once more. Even worse, they learn that the mass-murdering Ethros demon does not pose the biggest threat to the Anderson family's well-being. See also List of Angel (series) episodes.
"I've Got You Under My Skin" is a song written by Cole Porter. It became a signature song for Frank Sinatra, and became a top 10 hit for The Four Seasons in 1966. It has also been recorded by Lee Wiley, Steve Barton, Michael Bolton, Ella Fitzgerald, Diana Krall, Dinah Washington, Michael Bublé, James Darren, Cesare Siepi, Al Bowlly, Neneh Cherry, and many others.
Written in 1936, it was introduced in the Eleanor Powell MGM musical, Born to Dance in which it was performed by Virginia Bruce. It was nominated for the Academy Award for Best Song that year.
Sinatra first sang the song on his weekly radio show in 1946, as the second part of a medley with "Easy to Love". He put his definitive stamp on the tune ten years later, in a swinging big-band version that built to successive crescendoes on the back of an arrangement by Nelson Riddle. He usually included the song in his concerts thereafter.
In 1993, Sinatra re-recorded "I've Got You Under My Skin" as a duet with Bono of U2, for inclusion on Sinatra's commercially very successful Duets album. It was also released as a B-side of U2's "Stay (Faraway, So Close!)" single.
