However, rather than focusing on what makes one better than the other, let's determine why both of these two esteemed artists were so popular and still deserve attention. They both pioneered a form of loud, up-beat piano in combination with a form of oral serenading that was both ridiculous and ridiculously vivifying. I beg to make the case, that Bruno Mars, in his song "Treasure", drew some inspiration from Jerry Lee Lewis' "Great Balls of Fire". The "mine oh mine" at 1:40 sounds familiar.

Furthermore, the Bruno Mars band setup looks a lot like the live performance from Little Richard. Hopefully, the uplifting musical spirit of Little Richard and Jerry Lee Lewis will prevail!
