Shame about the keys - Paul, learning the bass

I bought this to give me some music to practice with when learning an instrument to play in our worship group. In general it has been worth it, but, unfortunately, some of the songs (about a quarter at a guess) are sung in a different key from that published in the SoF music books - this makes it hard to play along with the CD for those songs. It would have been best if they had all been in the key published in the music book, but it would have been OK if they had at least mentioned in the booklet which key they were actually in. As it is, I've either had to ignore those songs, or try to guess which key they are in (which isn't easy when you're learning).
