Did you ever hear the Sugar Ray version of this song? It's Rivers' song but it came out before the Raditude one.
Haha, I ended up listening to that Sugar Ray album a few years later and was surprised to find it was the same song! I assumed it was a co-writing thing between him and McGrath...
I think it's all Rivers. Not positive. The Sugar Ray one sounds like it belongs right on Make Believe to me haha.
