Yep, that's what Grant was asking about. There were song books containing the sheet music for *most* tracks on Pure and Odyssey, arranged for piano and guitar. I don't know if there will be one for Treasure but I see no reason why not.
Thanks for the answer Toronado and Roger. The song book for "Pure" is available on Amazon France so I have been wondering for a while if I would purchase it or not, but now I know I won't buy it because I can't read sheet music anyway.
I bought the two songbooks from a local music store. Hopefully, you will be able to do the same. If it helps, they are both currently available at amazon.co.uk. The biography also appears on the same page!
Don't forget that in the songbooks, you get the complete and official lyrics of each song included, this enables you to sing along as you play (except for those like me who can't play! )!
I am sure that in due course, the Treasure book will become available. All good (specialist) music shops in the UK are likely to stock it and I am lucky to have one such shop in my town (Kimbers Keyboards).
Just to add a little bit of info. The books for Pure and Odyssey are actually quite expensive if bought in the High Street, so I purchased from Amazon.co.uk at quite good prices, when the time was right.
Incidentally, I neither read music or play the guitar (or any instrument for that matter) but I've added them to my collection for completeness.
