Like Liz I sing every day, either along with a cd in my car (when my son isn't playing heavy metal, he can't stand folk any more)or when I'm gardening or working in the house. Using an MP3 player can prove embarassing, I was trying to learn the words to a couple of songs at work when I realised I was getting some odd looks from the others in the office and realised that I was singing out loud. But I think we are in the minority. Go to a church wedding/christening/funeral and how many people do you hear singing?
