"Fool That I Am" is a song originally recorded by Etta James and featured on her album, Time After Time. It was later covered by Adele and featured on her EP, iTunes Live from SoHo. A live cover of the song (performed during a live performance at Cambridge) was released as the B-side to the re-released version of Adele's debut single, "Hometown Glory". "Hometown Glory" was included on Adele's debut album, 19. ("Fool That I Am" was not.)
"Fool That I Am" replaced "Best for Last" as the B-Side to "Hometown Glory" when it was re-released.
Adele never actually recorded a song in the studio and instead only sang it live, where it was recorded and used for the B-Side of "Hometown Glory". Adele has described the song as something that changed her life. It was performed during her An Evening with Adele tour, one of her first live covers.
When asked about "Fool That I Am" and why it was the B-Side to "Hometown Glory", Adele stated:
|“||Etta James is my favourite singer. I`ve loved her ever since I was 15. Initially it was because I loved the way she looked - the big kinda white-woman weave and her beautiful, catty eyes! But then, once I actually listened to her, though she didn`t really even write any of her own songs, I found that her delivery was just so sincere that she really could convince me she was singing directly to me. Which is something I`ve never ever found in any other artist. So because - with me only having one album - I felt I needed to beef-up my live set by introducing covers, I decided to include 'Fool That I Am' in my show. You know, it was a song that just changed everything for me. It inspired me to want to write my own songs, to be honest and to try and touch people. Basically I think it`s a beautiful song, I love singing it... And so I thought it would be nice for my fans if I included it on this single. ||”|
Adele told the audience at one of her shows that this was her favorite Etta James song. 
This is one of the first songs for Adele to cover in her career.
