I was interested about the origin of the infamous "Shack song" however I must disagree witn "magician" concerning the origin of the verse concerning the Mig.It could not have originated from the late sixties or be related to a North Sea Exercise. Firstly I was a member of 205 Squadron in 1965/6 at Changi in Singapore and we were singing that verse on many an occasion especially when we went on detachment to Kuching and Gan and were celebrating in the respective messes. Secondly the MiG (all the variants around at that time namely the 15,17,19 and 21) were limited range aircraft and were unlikely to even reach the North Sea,there were no significant Soviet naval aircraft forces at the time, the Moskva was not around before the seventies and that was limited to helicopters and VTOL aircraft so unless the aircraft had flown from East Germany overflying various NATO countries then that story leaves a lot of questions.
I think that the story of the Mig must come from the fifties or possibly the confrontation period in the early sixties assuming that Indonesia may have had Migs. I must admit that I do not recall any tales of MiGs being in conflict with our forces during Confrontation but Indonesia did have soviet helicopters so it is possible that they had MiGs as well.
Anyway thanks for the verses I had forgotten parts of the first verse,in fact if my memory serves me correct there was a total of at least 4 verses.Does anyone recall the other verses?
