If I was Marler I would be tempted to claim that I was singing Leonard Cohen's "So long, Marianne" to myself to keep my spirits up, as the third line of that is "you know I used to think I was some kind of gypsy boy". Simple solutions are often the best. Perhaps he could post a solo acoustic guitar version to YouTube by way of illustration.
A Bm Come over to the window, my little darling D A I'd like to try to read your palm G D I used to think I was some sort of gypsy boy F#m E Esus4 E E7 before I let you take me home [Chorus] A F#m Now so long, Marianne, It's time that we began E Esus4 E E7 E Esus4 E E7 A Asus4 to laugh and cry and cry and laugh about it all again
I was also looking - as you do - at the French Wikipedia page about Guy Novès, les Blues' coach ahead of the France England game on Saturday evening. It says that his nickname is le sorcier le gitan.
Rendered in English le sorcier le gitan is the gypsy sorcerer.
This one will run and run.
