Thank you Kayakamina.
Of course Aaron's Rod by Lawrence, but misled myself by filling in 'red' instead of 'rod.' I was thinking along the lines of past tense of read (sounding like red).
As for Upmarket. As you saw I had it, but didn't actually know why. So please explain thanks.

Thanks Kayakamina. Now that you have explained, I recall another ABer telling me that one went 'up' to college in UK. Too bad my memory doesn't retain such tid bits.
