Holy laughter

Had a fun night tonight entertaining a church guild with a few talented colleagues, one of whom was pointing out the irony it is that, in church, we usually sing the Old 100th in such a sombre way.
The words just call out for laughter:
All people that on earth do dwell
sing to the lord with cheerful voice
him serve with mirth his praise forth tell
come ye before him and rejoice.
Every line an incitement for merriment and yet we manage to make it thoroughly miserable.
It was wonderful to be with a group tonight and see and hear so much joyful praising of God.
I heard someone say recently that while laughter is good for you, gravity is on your side when you frown.
Even though it is Lent, let's defy gravity and indulge in some mirth.
