Matyilem has not been nearly as widely covered as more famous Roma songs like Ederlezi or Zaspo Janko, but there is a 2003 studio recording by another Hungarian group, Romano Drom; there is also a solo vocal and guitar rendition by Melinalida, a singer and dancer from the Netherlands. Melinalida has a very extensive YouTube playlist which contains lots of Gypsy music.
And last but not least there is a duet by Sam and his erstwhile singing teacher, Muriel Girard, accompanied by Les Tziganes du Bocage, recorded a few years ago in Normandy.
