Tift reports on Facebook that she's be a'buskin'. I had to look it up.
Imagine walking through the city and coming upon Tift singing for pennies on a corner, while on vacation.
London may be too cold for outside busking... but the BBC studios were warm on Thursday when Tift recorded her session with 'Sir' Bob. Goes out on air during Bob's show on 27th May, I'll post a link if I remember at the time. UK and Euro folks will have to wait for live shows until "late summer or early fall" according to Tift on her Facebook page. Pic from Thursday's recording on Bob's website
