A marathon concert season at the Olympia - 18 days of two, sometimes three shows each, on a nine-act bill. At no time was it clear who was headlining...The Beatles, French chanteuse Sylvie Vartan, or Trini Lopez, the US singer famous for "If I Had A Hammer", although it was the Beatles who closed each performance. A part of today's matinee was broadcast live by the French radio station Europe I in its programme Musicorama, from 1:00 to 2:00 pm. Listeners heard Trini Lopez, Sylvie Vartan and then five songs by the Beatles.
