Following are some hymns with chords, so you can play them on the piano or guitar. I don't like typical hymn-playing piano, but like to embellish and play in a more modern style. I also like to throw in some additional chords at times ... especially minors. So you may find some of the chords unusual if you are used to these old hymns, but sing along and I think you'll find that the chords work fine (at least I think so).
If you scroll down you'll also find some hymns using simpler arrangements. I'm not very good on guitar, and did these arrangements for my own benefit.
You may find some of the following in a key more difficult to sing. If so, you can try using a capo (if playing guitar), or try a more difficult arrangement above. I did these for my own benefit, as I am not very good on guitar and needed to have a simpler arrangement.
