Well, since I can't dance, and my singing voice is often painful to human ears (including my own) I think I'll have to pass on this one.
Green and purple would be ok though.
I know what you mean. When I sing my kids have two reactions: 1) that I sing solo, so low they can't hear me, or 2) that I sing near a window, so they can help me out. ;^)
