An earworm...

Iggy here:

For some reason, the address "16 Charing Cross Rd" in London popped into
my head a couple of days ago and my brain won't let it go until I figure
out why.  Since I've had no success yet, I'd like to ask all of you if
anyone knows what's at that address, if anyone knows, and if anyone can
help me figure out why it popped into my head...


Thanks
