My special guest on today's Lockdown Listen  tells me that, by all accounts, it's been more than 30 years since he made an appearance on the BBC Northwest radio programme Pedal, Percussion and Pipes presented by our good friend Alan Ashton.  Nonetheless, Norman Scott has maintained a hugely popular profile in the region, playing theatres, halls and electronic organ clubs. Well we met after a concert in Llandudno, North Wales in 2005. And the first question I asked was in what ways had his craft changed over the years.
