Sorry to everyone who didn’t get to see this shout-out from Bob Dylan, but the codes for this video have suddenly stopped working in my blog, even though I didn’t make any changes.  I tried replacing them, but with no luck.  If anyone knows a little about embedded codes, could they help to explain this?  Can codes expire?  Normally, I would delete this post to keep my blog looking tidy, but I’m hoping it some responses to this post can help me learn a little more before I place codes from other sites in future posts.
