At last, Avalon can be found on an Ordnance Survey Map. It appears to be located in a suburban park in East Belfast. In fact, as I type, I could walk there in 10 minutes. I’ll pass on the Afterword’s ‘hello’ to King Arthur, Sir Lancelot, Guinevere, Merlin, Sir Galahad, ‘Justin’ and all the rest of the guys. I fully expect to find a short fat man in a Blues Brothers outfit in a paroxysm of transcendence, “playin’ R&B with the fauns and the satyrs, eatin’ pies with Reepicheep an’ Aslan, Mahalia Jackson comin’ through the ether, Bix Beiderbecke and Georgie Best crossin’ the bridge, take me back, take me back, take me way back…” etc etc etc
