"Welterusten, meneer de president" (Sleep well, Mr. President) is a Dylanesque song from 1966, sung by Boudewijn de Groot. Like most of his other songs, this one was written with songwriter Lennaert Nijgh . The music was composed by Boudewijn de Groot himself. The song is a protest against the war in Vietnam and the president of the US by the time, Lyndon B. Johnson and made De Groot a name as a protest singer.
The song consists of six parts and is drenched in sarcasm.
