Neptunus Rex:
A Wing Commander with an American wife certainly narrows the field. Could it have been the inimitable 'Bang Commander Wizzlegette?'
Had it been, they would both have laughed it off. When he was Staish at ISK, on NYE '67/68, he started a snowball fight with OC 206 in the Officer's Mess Bar!
Sure you got the date right NR? 206 lost an aircraft & 13 souls December 21st 1967. Surely no high jinks that year?
