Music to his ears?

We went for our daily walk and Ewan was not too happy about it. There were quite a few tears for the first 10 minutes, however, I made an interesting discovery. Apparently, I can sing- or so Ewan thinks! He immediately stopped crying and did not start again even after I stopped singing. Wierd. We all know that unfortunately, I do NOT have the gift of singing ability. But, my little man appears to enjoy it- which just cracks Denny and I up!!!!
