I have always loved this song since I was a kid and I love the sessions behind the song. I have always wondered though
how are those paadings, paadings played? What I mean is the part before Billy and Carl's Guitars come in after Al Jardine sings. I know it's Brian and Carl but how are they playing it?
Here are Brian's Piano Parts roughly isolated from the 2012 Stereo Extraction
