Choir, as promised here is the log in details for the young voices site. I presume you simply go to the young voices website at www.youngvoices.co.uk and click the section that says children.
The log in username is: youngvoiceschoir (all one word all lowercase letters)
The password is the same: youngvoiceschoir
From here you should be able to locate the lyrics, some mp3 tracks and various other things so explore and practise at home. Have fun!
