Whether he is from The Wirral or Beer-kin-ed is neither here or there to anyone who is not from the area. He sounds like a scouser to me, like someone from Romford would sound like a cockney to you (but not me).
Years ago, when it was almost impossible to go to "my" pubs (I am gay) without some tawdry drag act on, I encountered Lily Savage many times - and he was no funnier in a frock than out of one. At least in that environment he (like all the others) could use foul language in place of wit, baiting someone in the audience then throwing a few screamed expletives down a distorted microphone at them whilst the assembled daft queens would fall about laughing. On TV he doesn't have that option.
Of course it's good we don't all like the same. I have a friend who finds Last Of The Summer Wine hilarious, and splits his sides whilst the rest of us look on, baffled. There are many comedians/light entertainers who don't rock my personal boat, but whom I respect for their intelligence and professionalism. I'm no Graham Norton fan either, but he is far sharper than O'Grady (and was genuinely funny when I saw him on the Edinburgh Fringe some 12 years ago - yonks before he was on TV).
No - I still think O'Grady is a third rate drag act that got (very) lucky with Blankety Blank.
