Last note - I loved those early Dave recordings with the "jibberish" lyrics. It was like a peek into his song writing process. I was always amazed that he would basically write his songs on stage, singing jibberish lyrics until something materialized over the course of weeks or months of playing the stuff live. It made for some great early music that was so organic and natural. His more recent stuff, which is largely written in studio, with the help of producers, has a different, wider market feel to it. Not necessarily better or worse, just different.
