Actually these aren't particularly obscure for Azed. The former is in my Webster's (!) and the latter in the OED. One of these days I'll have to hunt out a Chambers.
Thanks both, wasn't suggesting they were obscure. 9ac - oops, didn't spot the anagram, I was thinking hair (shirt)and couldn't see past that. I must have the last letter of my fish wrong as it's not in Chambers and the other letters all cross check.
