Fervent admirer of the pioneers of the musette and the "popular" accordion, I would like to bring a small precision concerning a monument of the piano with strap, Marceau Verschuren, more known under his pseudo "Marceau" and which signed its numerous productions under the acronym "Marceau V.", the "V" replacing the family name "Verschuren" or perhaps "Verschueren" as specified to me recently a nonagenarian who had the chance to know the family name "Verschuren". The "V" replaces the family name "Verschuren" or perhaps "Verschueren" as a nonagenarian from the suburbs of Lille who had the chance to listen to him in his Nordic childhood recently told me, so I am surprised every time the "V" is replaced by a first name such as Victor or Vincent or Valentin.
