Yes! You must mean the Meikleour Beech Hedges

The Stewarts of Blairgowrie were famed for a wide range of Traveller Culture. Belle Stewart was a great singer but unlike many in her family, she would rarely tell a story. If she was pressed to tell one it would be the one about the beech hedges.

(I wonder if there have been any threads on Mudcat that have been subject to as many cases of thread drift as this one.)
