Django Reinhardt married Florine Mayer in 1927 according to gypsy custom although their marriage was not registered, and therefore not recognised under French law.

[3] A private and rather shy individual, Lousson performed in bars in Paris through the 1960s, most frequently accompanied by fellow guitarist Jean-Marie Pallen,[4] and appeared several times at the Django Reinhardt memorial festivals Samois-sur-Seine.

According to author Michael Dregni, Lousson spent a number of years travelling in Italy, then returned to France in the early 1990s.

[6] At Samois in 1978 he is pictured using a Gibson ES-175 hollow bodied jazz guitar belonging to Django's brother Joseph.

"[8] Feeling unappreciated by critics and not accepted by French authorities as the legal heir of Django, Lousson retired from playing in 1980.
