I only tuned in about ten minutes ago, but what a lovely interview! It was so touching to hear about the fan letter that Shaun wrote to DS and Mark when he was 15 years old and it was returned to him with "Gone Away" written on the unopened envelope, unknown to MK! Shaun showed MK the letter and Mark read it, live on the radio! I'm afraid I was welling up at that point! I hope I can listen again!
EDIT: The letter is still on the website, read by MK!
