Give Me A Reason - Piano

Give Me A Reason is available in the In Blue book available from that link.
It is also in the The Best Of The Corrs book.



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.
