Hearing loss was either listening to the Rolling Stones full blast or jet noise. "Paint it Black" was my favorite.
No hearing aids here yet, but not far off I'm sure. Jimmy Hendricks was more popular during my time.
70 - 71 I spent some time in Vung Tau & Tan Chow. Do you know these places?
I remember going to the Filmore in San Fran for a concert with The Who, Big Brother and the Holding Company and Jimi Hendrix. It cost us 3 GI's 75 cents each and once inside, a hippie chick gave us an apple to eat. On Janis' break..she said to us "y'all three look like GIs"." We are!" I said. "Come here boys an help me polish off this bottle of Southern Comfort" said Janis. Long story short we did. What a night we had.
