While waiting for BPB yesterday we heard faint Block Party Bash music coming down the parade route but there was no parade coming and the Introduction announcement had not yet commenced. We finally realized that the music was coming from the traveling scooter ODV which has now been equipped with a small sound system.
It was playing a similar but kind of remix version of Block Party Bash and it did not include any of the copyrighted songs featured in the parade (assumedly the reason an official CD has not yet been released). I asked the CM on the ODV if that was from a CD available for purchase and he said he did not know but thought so. We forgot to check if there were any new CDs available for purchase but I have a feeling there will be. Maybe it will be on a finally-updated DCA CD?
