Artist names and their changes:

[bob_32_116]

Rain = Oasis, you are quite correct Ruby:

Rain was taken as their original name as it was Liam's favourite Beatle song, came off the Revolver album,
when Noel started writing original material the name was changed.

as for your two other contributions, i'll have to go away and think about them, thanks for joining in and participating in the game.

all the other missing/incorrect names in my list will now be posted.

I would never have guessed The Beatles, because I thought the line-up as we know it did not happen until they were calling themselves the Beatles, or possibly the Silver Beatles, certainly not while John and Paul were calling themselves The Quarrymen.

Starfish/Coldplay: I don't know why they started with the name Starfish, but it has apparently been a popular band name; there have been at least three bands called Starfish, which may be why they felt the need to change their name. I am curious (Yellow) about why they chose "Coldplay". Does it mean something?

As for #10, you'll have to explain that one. Was there an amputee in the band?
