Errant lyrics

We just arrived back from Oregon last night so I have some pictures to share, but for now I'm just going to pass along this little lyric. Every night at Grandma and Grandpa's, Grandma sings songs with Bella before bed. Last night they were singing Amazing Grace, and as Bella sang along with Grandma the lyrics went a bit like this: "Amazing grace, how sweet the sound, that saved a wretch like you." I don't think she quite gets it.
