Songs for an Epiphany

We all have them, those songs that make us think of our defining moments. Some of those songs may have even inspired us or spurred us on. I was driving home today listening to the radio, when Miley Cyrus' crossover hit, "The Climb", began to play, and ended just as I pulled into the driveway.
Some songs are related to our youth. I remember "Mairzy Doats" as my momma sang it to me when I was a little girl. I also adored a 45 rpm record I had of "the Smokey The Bear song". There were children's shows on Sunday morning. One involved a double decker bus that led to an underground clubhouse set somewhere in England, I am sure. I remember one of the older girls, sat in a rocking chair singing to a smaller child a song about "Granny's Rocking Chair" and how you could travel anywhere in said chair.
I remember dark cold mornings waiting for the school bus and the long ride, listening to the bus' radio. We were lucky to be among the first on, and able to choose seats beneath the speakers. I loved the songs of my teens, and sang lustily to "Little Willie" and "Bohemian Rhapsody".
I remember sad songs, such as "Sad Songs", or "Daddy Don't You Walk So Fast". I daydreamed to "Love me, Love me, Love" and "Music Box Dancer" and "Heaven on the 7th Floor".
Then, there were the songs we fell in love to. For Ralph & I, it was Donny Osmond's "Sacred Emotion". Corny, yes I know. I also got stirred up a lot listening to the reggae version of "This Magic Moment" that was used in the movie "Cocktail".
I have to devote a separate paragraph to the Beatles. Their music was so much a part of my life's memories and defining moments. I remember listening to them on Spring Break trips to Kentucky riding in the pickup camper with my older brother. I loved "Hey Jude" and "Paperback Writer". The collected works of the Beatles are so numerous that there is virtually at least one Beatles song defining moment in most of baby boomers lives. I would like to know your Beatles moment & song.
I know for many, Michael Jackson offers similar associations as the Beatles as defining their memories. For others, it may be country or Christian music. For example, my daughter's early years were spent loving Dolly Parton's "Coat of Many Colors" and she adored Mary Kate & Ashley's kids songs and Kid Songs' kid songs.
I know everyone has a story and every story has background music. I have songs that play in my head for every memory I revisit. I even have songs that evoke thought of certain people. For my late friend, Anita, the song "Stronger" by Britney Spears makes memories rush back.
I am certain that "The Climb" will define a moment for somebody. There is a place for comments, please, leave a comment with your defining moment & the song intrinsic to it.
