Snap-back songs

[Leg]

I have 3 songs that snap me back to specific times and places in Vietnam whenever I hear them today. I am not going through a flashback, but they cause me to freeze up and stop whatever I am doing as I re-experience the smells, sights, and activity of the time.

1) Im So Lonesome I Could Cry (Hank Williams, Sr.)
2) Aquarius/Let the Sunshine in (The Fifth Dimension)
3) Those Were The Days (Mary Hopkins)

[No, exlrp, I didn't listen to them while on an ambush ]
