Say - Piano
Say is available in the In Blue
book
available from that
link.
Many of the songs are also available from multiple sheet music
download sites.
Disclaimer: I've never used
any of these sites so can in no way what-so-ever vouch for them. I
just found them by a basic search on Google.
Here's a list of links to some of these sites that I
found have Corrs songs available. Most have them listed in
alphabetical order.
