Thanks for the BBMF link OldPilot55 - I agree with both you and Grob Queen the Lancaster would the best choice however after already visiting the BBMF website and a few others during my research, it seems unlikely the RAF will agree to a flypast for a 'just' a wedding. Fair enough, not being blue blood an all.

The reality of normality is I think a privately owned Spitfire. With that in mind thanks for the link Grob Queen I'll be checking those exceptionally well minted Spitfire operator chaps out first thing on Monday morning.
If anyone else wishes to chip in - from rumour to something a little firmer - please do.
