Me too!
Another more elaborate setting by the Vienna Boys' Choir, which has all the verses: In dulce jubilo
IN DULCI JUBILO
1. In dulci jubilo,nun singet und seid froh!
Unsers Herzens Wonne leit in praesepio,
Und leuchtet als die Sonne matris in gremio,
Alpha es et O, Alpha es et O!
In sweet rejoicing sing and be glad! Our heart's desire lies in the manger and shines like the sun in his mother's lap. He is Alpha and Omega.
2. O Jesu parvule, nach dir ist mir so weh!
Tröst mir mein Gemüte, O puer optime.
Durch alle deine Güte O princeps gloriae,
Trahe me post te, Trahe me post te!
O little Jesus, I am so sorry for thee! Comfort my soul, O best of boys. By thy great goodness, o Prince of Glory, draw me after thee!
3. Ubi sunt gaudia nirgend mehr denn da!
Da die Engel singen nova cantica,
Und die Schellen klingen in regis curia.
Eia, wären wir da, Eia, wären wir da!
Where are joys, nowhere more than there! There the angels sing a new song, and the bells ring in the King's court. Oh, if only we were there!
