I asked the folks at Decca Classics, including the guys who just put together the excellent new
"Mono Years 1944-1956" box set. All of them said, in essence, no way. The technical guys said it's
not possible to cut 20-minute LP sides this way and there was no reason to do it, given Decca's
advanced cutting techniques developed during WWII, many of which were ported over to microgrooves.
For 78's, they said again there was no reason to cut a disk backwards since they could easily
accomodate FFRR cutting forward like everyone else. Unless someone can come up with some
documentation saying otherwise, I would say this is a MYTH and should be nipped in the bud here.
