Billy sang the 7th inning stretch at the Cubs v Reds game this past monday night (August 12th).

MLB on youtube have uploaded Billy singing, but you can download the full video including both interview and song from our media page (mp4 format) and you can also check out the previous times he has sang over the past 10 years as well – new site visitors, you’ll be wanting to browse all our videos.

Billy’s SLOWGIRL co-star Rae Gray also shared a  great image and video from the night.
