I'm glad I persevered and found the studio version of Lady Luck over the weekend. The live track on You Tube appears to have two ocean liners in the audience alerting each other to their presence with loud foghorn blasts.
Laid back and chilled this would be a great addition to a background mix tape for those romantic evenings. As a stand alone track it's pleasant but not ground-breaking, so probably not his first smash. Jamie has a great voice, check out the Al Fresco version on You Tube to hear it in its full glory.
