This is impressive, especially remembering all the exact lyrics after all those years, but hey, he's Paul McCartney!:) I usually have decent memory for tunes:

This is impressive, especially remembering all the exact lyrics after all those years, but hey, he's Paul McCartney!:) I usually have decent memory for tunes: some I can sorta play at the 1st listen, others need a lot more time, not necessarily related to their difficulty, but nothing special. However the most accurate memory I have is for sounds, or actually how a song sounds in its whole: I have on some occasions guessed a song, artist and title, just by listening just one second of it, probably less, while for example a friend was quickly changing stations on the car radio. I have never been able to give an explanation of this, but happened a few times. Sometimes I guessed the wrong song but got correctly the artist and album, which reinforces the idea that I could have memorized the sounding (that album sound) rather than the song structure itself, which probably would have been meaningless when mentally decoding such a short sample.
