Hi all<br class="">
<br class="">
I’ve been thinking about trying to do this. If you don’t mind wearing a mask when we sing closer than 10’ from one another we might attempt in, say a 10-person per time group. Those of you who have been to my house know that there is plenty of room to spread around. I can provide mics and amplifiers for a few people and guitar accompaniment; it might be fun to do rounds and a cappella too if we can hear one another. <br class="">
<br class="">
If interested, let me know and we can make arrangements. <br class="">
<br class="">
Love to all. <br class="">
