Certain songs take me back to specific times. I hear them and I'm somewhere else...in the past.
Knights in White Satin. I was coming back from Europe in 1967 on the old Queen Elizabeth I and every night I'd gather with another bunch of young folk to dance in the ballroom. One of the guys would slip a bill to the ensemble to play that song and we'd dance to it.
Put Your Head on My Shoulder. I was in the 8th grade, attending the Friday Night Junior High dances at the YMCA. I have a great dream that a dream-boat named Wayne, would ask me to dance and they'd be playing that song. Of course, that was a very far-fetched dream and he probably wouldn't pee on me if I was on fire.
Hey Jude. It was 1968 and I was driving down Hampton Boulevard on my way to class and that came on the radio. I had to pull over to the side of the road. I COULD NOT drive and listen to it at the same time.
Pretty much anything from Crosby Stills & Nash (pre Young). I hear that music, close my eyes and I can smell hot dust and diesel fumes. I'm back in Turkey, young married and a baby on the way.
There are a lot more, but those four can definitely make me time-travel.
