I seem to be stuck on BD in my acrostics

The following piece was a part of BD Birthday celebration wish, but now it seems to be proper to post it here:
Be ye cheerful, be ye mirthful
Ale be flowing, sing ye gleeful
Rare be anger, beef be roasting
Real be made yer table boasting
Oft be singing, rare be weeping
Wood be burning, bones be heaping
Dark be fearless, stars be shining
Oft together ye'll be dining
Wights be feasting, minstrels derry
Night be dancing, morn be merry
Sing ye joyful, sing together!
