In dulci jubilo ("In sweet rejoicing") is a traditional Christmas carol. In its original setting, the carol is a macaronic text of German and Latin dating from the Middle Ages. The tune is also famous from Mike Oldfield's 1975 version of it, which was performed in the opening ceremony of the Olympic Games in London 2012
IN dulci Jubilo, Now lat vs sing with myrth and Jo
Our hartis consolatioun lyis in præsepio,
And schynis as the Sone, Matris in gremio,
Alpha es et O, Alpha es et O.
O Jesu pervule ! " I thrist sore efter thé,
Confort my hart and mynde, O puer optime,
God of all grace sa kynde, et princeps gloriæ
Trahe me post te, Trahe me post te.
Ubi sunt gaudia, in ony place bot thair,
Quhair that the Angellis sing Nova cantica,
Bot and the bellis Ring in regis curia,
God gif I war thair, God gif I war thair.
