Alanabit,
One man's overplayed song is another's bread and butter--Country Roads was always heavily requested,followed by equally heavy tips--I make no excuses, as I always needed the money--

For my most over-requested songs though, when   I worked as a strolling musician with a balalaika player, in addition to the usual real Russian and Gypsy songs, we usually had to play "Lara's Theme" at every table. "Those Were the Days" was a close second, with more than a few calls for "Sunrise, Sunset"--
