I keep thinking Tintagel for some reason.
Tint = Shade, but can't make the rest fit.Then I thought of Nigel ( Kennedy ) Violinist. Can get Nigel out of Tintagel and that leaves TAT. Hope you can understand all that.
We thought of TINTAGEL Valerie (that's my name to) but have used that for - According to local ledgend it's the site of King Arthur's Camelot. Perhaps I better look at King Arthur again. Thanks for taking the time.
