Seeing as I've played covers of these songs in my band, I couldn't help but notice the chorus uses the same chords in the same progression (D to G and F to C, then repeat). Could it be that a certain amount of touring with RHCP rubbed off on Rob, and his sub-conscience shoved it out in the mix, or secret STP/RHCP friendship dealings allow them to use each other's material? Silly speculation or concrete fact? YOU decide >)
