I'm a big Lonesome George Thorogood and the Delaware Destroyers for man reasons. In a way, he's a local guy (Delaware is reasonably close to Philly, right?). I loves me some blues music, and Thorogood's guitar work is certainly a good representation of the blues. George's crackly voice just adds to it. Plus, the songs that he's either written or covered are classic blues.
Take "One Bourbon, One Scotch, One Beer" for example. This is truly the perfect song to play at a corner watering hole. First, it's long. Second, it involves drinking. Third, much of the song takes place in a bar. And, don't forget the chorus - most bar patrons know it, and love to partake in singing the chorus.
The lyrics themselves are what blues is all about. It's about being kicked out of your apartment, not having a job, and losing your woman ... - "Well, I ain't seen my baby since I don't know when ... I've been drinking bourbon whiskey, scotch and gin ..." And on top of all that, the guitar work is awesome.
Just have a listen:
