As long as nobody describes YOU as a flat, sour holey thing Steve, you needn't feel depressed. And the holes are essential to allow the BUTTER (not horrible old olive oil) to melt and permeate the crumpet.
Thank you leeneia for your advice on getting rid of earworms. I'll try your second suggestion. I've been humming some of Enya's songs, and they're good for displacing other stuff. Trouble is, like the old lady who swallowed a fly, you then need another song to displace Enya etc etc.
It's true isn't it Steve, the tune does sound authentic. The two identical lines followed by a third which is different is rather Celtic in form. I reckon it's a Scottish song.
On my tombstone as an epitaph it will say 'She never found out what that song was' RIP.
