The Next 30 Day Song Challenge - day 07

Day 7 - A song you discovered through a TV advert

For the life of me I can't remember the actual advert itself -  the lyrics make me think of life insurance and/or mortgages for some reason -  but I do know that once I heard the 15 second clip of Ella Fitzgerald singing 'I Wonder Why', I just knew that I had to find that song. I think it took me two years to eventually track it down. Go figure.
