Tis a silly quiz. Although the martlet question made made a fool of us. I'm not sure that knowing when a concert took place qualifies one.
Now, if they asked questions about the number 17 that would separate us from the DFL folk.
7/10. I didn't know the album or the concert one.
Now for the real embarrassment. I thought a Martlet was a real bird. Forgivable, perhaps, but I work for a nature conservation charity....
