On my site you now can find the two tracks Earth and Doin'Alright. These are the versions before Brian May's vocals were edited in. Completely sung by Tim Staffell. Btw, I think Tim's cd aMIGO is worth buying, for the new versions of these tracks with Brian's co-operation. The whole cd is worth listening to.
"Hi RIEN, I have got the cd too (signed by tim) and I think these tracks are with brian. I'm not sure"
As Rien said, they are versions where Tim sings all the lyrics. Probably from the promo-cd sold at the fanclub convention this year.
I thought the promo CD from the Convention was identical to the "common" version of the album? Except that it was some signed limited edition, of course.
In the limited edition of AMIGO (200 copies signed by Tim), are includes the same tracks and the same versions that the normal cd. (I got the 2 ones)
Brian played the guitar in EARTH and made backing vocals in DOIN'ALLRIGHT.
