Remember the "oil shortage" of the early 70s? That was the reason given at the
time. Thinner records, lowered speed limits, switching Daylight Saving Time
around..I remember it well. Now they just jack up the prices on everything.

There was another odd thing that turned up on an RCA pressing I remember from
about 1966 and I wonder if it happened everywhere or just on the Canadian issue.
The Khachaturian Piano Concerto, played by Lorin Hollander, had several odd
metallic clunks during the second movement, like somebody tapping on a
microphone, I kid you not. I wonder if someone was touching the gate on the tape
deck being used for the transfer or what caused it?
