Peel Show of 6 april 1991

[Vince Nzo]

Hello,
I was listening to a John Peel Show dated in the Wiki as having been aired on 6 April 1991 but this seems to be the wrong broadcast date for this programme. Just before the episode of Vivian Stanshall's Sir Henry At Rawlinson End commences, at about 70 minutes into the programme, Peel himself states that this show is from Tuesday 9 April.
What's your opinion?

All the best,
Vincent
