Are many Shadows enthusiasts in search of single Muslim women? Mr. Google (or his algorithm) obviously thinks so, since an ad for single Muslim women keeps popping up when I select this site. I tried to think of a few gags based around the titles of Shadows tunes that might have a connection but some people are very touchy about that sort of thing so I had second thoughts, but if anyone's brave enough . . . . . . . ?
