The eighteenth day in the 50 Day Music Challenge is 'a song you never get sick of hearing'.
I have MANY songs I never get sick of but one that has stuck since high school and only got stickier after I saw him live is Brian Adams' 'Summer of 69'.
I cried when I saw this live. Seriously.
In high school this was one of the many songs of the group I was hanging with at the time. We sang the original version and our adapted 'Summer Doing 69' during lunch, on the bus, at parties, in between and in classes.
Here is one live version. Not from when I saw him, but even if it was it still wouldn't be the same as the first moment hearing it live.
