the Dutch Sesame Street, and produced music for other artists. Solo career From 1986 to 1991, Vrienten played oldies like "Teddy Bear's Picknick" with Magnificent Seven, whose members included singer/advert composer and unofficial fifth Doe Maar member, . A new solo album was in the pipeline but held back by the release of a best-of album. The expected Doe Maar revival never happened, and in early 1992, Mijn Hart Slaapt Nooit, Vrienten's third studio record, saw the light of day. As with Geen Ballade, the album received minimal promotion. At the end of the year, all Doe Maar members reunited to support the 1960s outfit CCC Inc., which featured Ernst Jansz and Joost Belinfante, at their 25th-anniversary concert. In the mid-1990s, a new generation of Dutch-language acts emerged, and Henny ended up collaborating with rap group Osdorp Posse. Doe Maar: the reunion: 1999 In 1999, the four-piece rock band BLØF spent a whole tour playing Doe Maar tribute shows. Doe Maar members attended the show at the Amsterdam Paradiso and on 1 November 1999, they announced their reunion for one last album and a 25-date tour of the Netherlands and Belgium, consisting of eight club shows, a record-breaking sixteen-night residency at the Rotterdam Ahoy, and a stadium show at the Antwerp Sportpaleis. The album Klaar was released in April 2000; the band were finally acknowledged by the pop critics who had previously criticized them for singing in Dutch. Further work: 2000–2022 In 2008, Vrienten recorded an album with contemporaries Frank Boeijen and Henk Hofstede (frontman of The Nits), titled Aardige jongens. They promoted it with a theatre tour. In 2010, Vrienten appeared in Ali B op volle toeren, a programme in which young Dutch rappers exchange songs with established artists. He contributed "32 Jaar Later", a sequel to the song that gave Doe Maar their first top 40 hit in 1981. In 2014 and 2015, he released two solo albums and went on tour, accompanied by his son Xander (Jett Rebel's bass-player at the time) and the three-piece rock band My Baby. In 2016, Vrienten formed the supergroup with Golden Earring guitarist George Kooymans and Boudewijn de Groot. They released two albums in 2017 and toured until March 2020 with a setlist of collaborative songs and solo material. In 2019, Vrienten and his son appeared in a self-made documentary on bass players, a sequel to 2013's Gitaarjongens, which explored the
