became Roger McGuinn.
And hasn't Keef played free with the s (or no s) in Richard(s).
Terence Trent D'Arby became Sanands Maitreya, becoming lost to all in the meantime.
And don't lets even mention Purple Bernard from the Paisley Underground. My keyboard don't have "squiggle".

...famously became Yusef Islam after converting to the Muslim faith.

Mr. Tafkap, when you have quite finished staring out of the window, kindly answer when your name is called.

...American AOR's answer to David Bowie - exists in a constant state of flux and reinvention, morphing seamlessly from John Cougar to John Cougar Mellencamp and then to John Mellencamp.

I am guessing that his next stage persona will be known as Cougar Mellencamp.

From his diary:

Things to do this week:

1. Phone bank. That balance in this month's statement has to be a terrible mistake.
2. Shaun is the new Yeats. Tell everyone.
3.Change name to resemble something likely to appear stencilled on a solicitor's door.

Is probably the most high-profile identity changer, what with all the Prince/Love Symbol/Prince nonsense.

Then there's Sean Combs, who changed his identity from Puff Daddy to P. Diddy to Diddy in what I've always assumed to be doomed attempts to be taken more seriously.

Just remembered that Colin Blunstone did a strange one of these, of course. Re-recorded She's Not There under the name of Neil McArthur.

you were after mid career changes but sixities pop singer Vikki Carr used go by the marvelous name of "Florencia Vicenta de Casillas Martinez y Cardona" which is frankly ace.

Jessica Stevenson, a well-known name with a claim to immortality as co-creator of Spaced, got married and changed her name to Jessica Hynes, applicable to her professional as well as her personal life. At least that was what she said she'd be doing; whenever I've seen her mentioned or interviewed in print or on telly since, she still seems to be billed as Stevenson.

I've often been intrigued by the continuing trend for female tennis players either to change their name on tying the knot or, more commonly, append that of their nearest and dearest to their own; then, when that person becomes less near and dear, the headed notepaper changes back again, viz Justine Henin(-Hardenne).

Still, it'll be most entertaining if a coming-together of two players results in our being able to cheer for Anastasia Pavlyuchenkova-Fish.

was the nom de plume used by both Melanie Harrold and Joanne Carlin,when with Hank Wangford, each of whom had had solo LPs out under their own name. Surprising as they were but one person.
I saw her sing as one of 3 girly singers with the Albion Band, alongside Julie Covington and a then relatively famous black british jaz singer, whose name escapes me, Verona, Vikki something?

They'd never have got that lot onto a 7" label anyway.
Also, didn't Elvis Costello buck the trend by reverting to Declan McManus at some point, or am I confused? He was certainly The Imposter for a single, but dropped it after, so he's out.

Here's another that goes further than a mere name change.
50's/60's arranger Wally Stott (responsible for The Beverley Sisters' 'Somebody Bad Stole De Wedding Bell' - find it, please) had a sex change and became known as Angela Morley.

Of course, Walter to Wendy Carlos, Wayne to Jayne County, David to Dee Palmer

Johnny Rotten to John Lydon

Goodbye

Ah Chris G ,A Danny baker fan i Believe,
Hank B Marvin springs to mind. Where did the B go ? Did teh other hank Marvin sue ?

Okay, trivia fans. The villain in John Landis' Trading Places is called Clarence Beeks. Did you know that was the real name of jazz vocalese pioneer King Pleasure? Thought not.

Surely goes to the great Russell Bell - singer with billowy shirted new romantics Dramatis, circa 1981.

He changed his name to Rrussell Bell. Yes.

Kenny Jones.
Kenney Jones.

Reverted to the original Craig Ferguson, went to the US, now a TV chat show star etc etc
