“Homeward Bound” by Simon & Garfunkel.
It was really hard to choose because my dad loves music and has played guitar for almost 60 years. He’s still active in the local music scene and plays a couple gigs a week even in his 70s.
But I picked this song because when I was a kid he was in a folk duo that practiced in our basement. This was the last song they played at their gigs, and the last one they played at practice.
I was in elementary school at the time so my bedtime was right around when they’d be wrapping up and I have a core memory of hearing my dad singing it wafting up from the basement as I drifted off to sleep
