I remember a conversation between a certain ASCOT (VC10 C Mk 1) callsign and Jax centre when we were operating MZBZ - KIAD in the early 80's and it seemed that we were the only aircraft in the night sky.
Jax centre: "Ascot 2276 are you area nav equipped?'
Ascot 2276: "Well, we have LORAN, OMEGA and a Navigator with a sun gun."
Jax centre. "Good enough. Cleared direct ARMEL TACAN (800+ nm). Be advised RUMOURS bar is staying open pending your arrival."
Happy days.
