“Maybe I’m Amazed” is a song written by Paul McCartney that was first released on his 1970 album McCartney. McCartney dedicated the song to his wife, Linda, who had helped him get through the break-up of The Beatles.
A live performance by McCartney’s later band Wings from its 1976 tour of America was released as a single and became a top-ten hit in the United States and reached number 26 in the United Kingdom. The original studio version from McCartney has never been released as a single.
Listen for Paul singinging during the guitar solo, according to Bobby Owsinski, he favors a 175 millisecond delay on his vocals both in the studio and live, and you can hear it here, with a little bit of a short reverb tail on the delay as well.
