Rocky Mountain High

"Rocky Mountain High" by John Denver is the top-selling single of his first Top 10 US album that bears the same name; the single ranked 29th on the Year-End Billboard Hot 100 of my birth year. The song narrates a story, but I wasn't sure of the references and imagery - this Songfacts article was most insightful.

He was born in the summer of his 27th year
Coming home to a place he'd never been before
He left yesterday behind him, you might say he was born again
You might say he found a key for every door

On the Hot 100 list, "Love Me Like a Rock" by Paul Simon was 27th, "The Morning After" by Maureen McGovern 28th. I remember including the McGovern hit on my "Gurlish Emote" playlist many years ago, a collection of 1970's feminine swoons built with the help of Limewire.
