Musical Ornaments - Round 2

Sorry it took so long for me to get to Round 2, but it's the last week before Winter Break, and I haven't been home when it's light enough to get a good picture. First, everyone who posted a comment or emailed me had the correct answer to Round 1. Good going, kids! Today, three different pairs of ornaments exchanged places on the tree. Can you find them? Be brave and give it a try. Remember ... to make it easier (especially for the old folks like me) you can enlarge the pictures by clicking on them once. Since vacation is very close (less than 24 hours, thank goodness), I'll try to be back soon with Round 3. If I'm having too much fun to sit at the computer, surely you'll understand. Won't you?
