Wonderful song made famous by the Everly Brothers (by the way featuring Chet Atkins on guitar). Written by Boudleaux and Felice Bryant, who also hold responsible for mega hits such as “Bye, Bye
Love“, "Wake Up Little Susie“,"Hey Joe" (Carl Smith, not Jimi Hendrix) or “Love Hurts“.
Based on I-IVm-IIm-V turnaround, making use of the extended dominant (G7) in the ending of the bridge. Nothing special to mention.
