William Daniels, the voice of KITT is supposed to be interviewed on the Colin & Edith Show which airs on BBC Radio 1 in the UK, tomorrow (Friday) sometime between 1pm-3pm GMT (or 8am-10am EST). The topic of the interview is unknown, but the station has been playing alot of clips of KITT, so one could only assume.
There is a stream available for those who are not in antenna distance of the station. You just need a copy of the Real Player, which is available for free from Real.com.
