Joel was performing one of his ‘party pieces’ by smashing a can of beer against his head until the can split, then taking a swig from it and lobbying the rest of the can into the audience.
If you are a fan of blues oriented classic hard rock then you can have a look at “More Than One Way Home”. You’ll find some pretty good rockin’ tunes on here. However I dislike the lack of own creativity. If you can overlook the fact that this band sounds exactly like another big one, then you can add one point more to the score. Solid classic rock!
