Jackson and Warren in 76

I was looking on YouTube for some vintage footage of Jackson Browne (inspired by the concert the other night) and found this awesome Warren Zevon performance of Mohammed's Radio in 1976 with Jackson playing guitar and singing back-up. Apparently Jackson performed Warren's classic song Lawyers, Guns & Money on the first date of his current tour this year (but hasn't played it since, damn him!). I would have so loved to have seen that.
