I have a CD disk on order that for some reason is being shipped from the UK (it's by American artist Rhiannon Giddens). The arrival time is suggested to be a month. I imagine that mail within the UK is moving like usual, but it isn't crossing the pond with any alacrity because there are so few flights (that carry mail in the cargo hold). Who knows when we might get to see those stamps?

You're lucky they're putting the group on stamps; in the US an individual has to be dead for at least 10 years before the USPS will consider putting them on postage.
