MESSAGE FROM PHIL LESH ABOUT RYAN ADAMS
We regretfully inform you that Ryan Adams will be unable to join us for these shows due to personal reasons. We will miss his presence and hope to make music with him again soon. However, with rings on our fingers and bells on our shoes, we are delighted to welcome Joan Osborne to PLF. Joan will be gracing us with her angelic voice at both Vegoose shows next week. Keep your ears open, as we have some other surprise special guests appearing as well.
