The only thing I vividly remember listening to in RVN back in 1965 was the Beatles' "It Won't Be Long Now," which in my case I took to mean until my departure date, November 10.

Wouldn't you know it, it had started to cool down by then. Only about 90 degrees F. at night.

Considering the Zeppelins didn't exist before 1968, I suppose that's not surprising.
