^^^ I see that lyric being about Scott whether he admitted it or not. Anthony has mentioned a different line or two towards Cobain I believe... Californiacation is the main one, I thought maybe I had caught another one at some point... either way, it doesn't surprise me to have a line like that show up in a RHCP song since Scott and Anthony's circle of friends seemed to overlap at times. According to Mary's book, I recall a gathering or two for a birthday or something where both RHCP and STP guys were together.
I love that band though. I'm really glad they're out there doing their thing with a new album in 2016. There is just something very authentic about the Chili Peppers and Anthony, although different styles than STP... it reminds me of the authenticity I have gotten from STP and Scott over the years.
