This is my interpretation of the song. I know that the original music as written by Franz Gruber is different than this. But this key sounds better to me and it is easier to sing by most. Here are the chords with full lyrics, as all I have seen only have just the first or the first 2 verses. Arranged for easy printing in one sheet of paper. Have it ready 'cause as soon as you bust out the guitar on Christmas Eve, grandma is going to ask for it. So be ready.

^GSilent Night, Holy Night, ^D7all is calm, ^Gall is bright, ^C'round yon virgin, ^Gmother and child, ^CHoly infant so ^Gtender and mild,

^D7sleep in heavenly ^Gpeace, sleep in ^D7heavenly ^Gpeace.

^GSilent Night, Holy Night, ^D7Shepherds quake, ^GAt the sight. ^CGlories stream from ^GHeaven above, ^CHeavenly Hosts sing ^GAlleluia,

^D7Christ the Savior is ^Gborn, ^GChrist the ^D7Savior is ^Gborn!

^GSilent night, Holy night, ^D7Son of God, ^GLove's pure light, ^Cradiant beams from Thy ^GHoly face, ^Cwith the dawn of re-^Gdeeming grace,

^D7Jesus, Lord at Thy ^Gbirth, Jesus, ^D7Lord at Thy ^Gbirth. Edit #1: I accidentally submitted before I was finished, but above is my final version.
