Hidden Dangers of Cooper Book

I love the Cooper book. Not as much as the Denson, but I do love it. However, I must admit that there is a higher proportion of catchy tunes in the Cooper than the Denson. Hence, since our second mixed book singing, I have been humming Mercy Seat about 50 times a day. I've even caught myself by surprise-- I was singing it before I even realized I was singing. I like Mercy Seat, but come on already! If Mark considers this my just deserts for not picking songs from the Norumbega I may not have a rhetorical leg to stand on.
