Mysterious, moi?
I am indeed Maggie, and my lovely dad used to serenade me with a rousing rendition of that very unsuitable song about the Maggie May who walked down Lime Street and loved all the sailors. When I registered, it seemed Maggiemay was already on here, so I added a little extra, that may or may not stand for my second initial.
I've got another 'keen'... Ouch!
