Jack was fabulous!! We wanted background music for an afternoon garden party and Jack provided exactly the festive ambience we imagined he would. He is a wonderful music man, very versatile and intuitive, he just absorbed the vibe and played accordingly. AND he is an accommodating problem solver, too ;-> Jack was happy to haul his speaker from his location under the trees to the deck so that we could hook up the microphone and give impromptu speeches! We are delighted with Jack's contribution to our party. Thank you, Jack!!
