>>914 There's a screening of TNM in Berlin later this week, right? If Tom is going to be in Berlin and Luke brought him his guitar, then probably the BBC radio interview is prerecorded - otherwise Tom could have just picked up his own guitar in London. Though the radio interview could still be live via phone or satellite, of course.
Wonder why Tom needs his guitar... maybe since the birthday party was a big hit he's going to put on a one man show for the SI cast in Vietnam.
