An off topic PS - despite leaving in LOADS of time (outer SW London to Oxford) we had a horrendous drive - junction between M25 and M40 (usual route) was closed due to a multi-vehicle crash, so everything ground to a halt.
Thanks to a road atlas in the car I quickly found an alternative via the M4, which we thought would be far too congested in the circs, and at first the M4 was, so fearing that we’d never make it, we contemplated turning round and going home.
But thank goodness the traffic did thin, and we made it - not from the start, but at least in time to hear most of Gdd’s choir. 🙂
