Still another music hint

The song's title appears in the lyrics 15 times.

Today's post-wisdom-tooth-removal/birthday-wine-drinking practice was surprisingly good. We worked on the new choreography and of course since our coach was not there we decided to change it all around.

We realized quickly that it's probably not a swell idea to tell him "we just couldn't do the hard stuff you gave us so we decided to do this easier stuff instead." So then we worked on the hard stuff and it got somewhat better. I think we'll go with his choreography since after all, he is a professional, and we are paying him for this. Plus it's going to be good, if only we can do it without tripping each other!
