Bachelor parties don't exactly conjure images of Buckingham Palace royalty. On the contrary, the groom's "last night of freedom" might even seem anti-royal thanks to a reputation for wild nights of partying. Nonetheless, the British royal family has a long tradition of bachelor parties, known in the United Kingdom as "stag do's" (per Good Morning America). In 1947, leading up to his wedding to the late Queen Elizabeth, Prince Philip was so keen on kissing his singledom goodbye that he indulged in not one — but two — stag nights. As reported by Hello!, the late queen consort threw an official bachelor party the evening before his wedding at The Dorchester Hotel, where he and his friends drank plentifully. According to the outlet, the Prince had also held a secret party just days earlier.

 On November 14, 1947, Prince Philip gathered with twenty-four close friends at the Belfry Club in London. Per some event menus obtained by the Daily Mail, the prince consort and his crew enjoyed an elaborate dinner of turtle soup, foie gras, and an assortment of mixed meats. The gentlemen topped off their meal with crepes suzette for dessert. 

All in all, the gentlemen seemed to maintain a sense of dignity throughout the evening. The bachelor party photos published in the Daily Mail report show Prince Philip's buddies dressed elegantly in black tie. Only a glint of mischievousness is apparent in the guests' sly smiles.
