The Lana Sisters were a British vocal group formed by Iris Long in 1958, with Lynne Abrams.
[1] They put an advert in The Stage for a third member and got a reply from Mary O'Brien, who would go on to solo success a few years later as Dusty Springfield.
Initial publicity for the group claimed they were three actual sisters with the surname Lana: Iris (or Riss), Lynne, and Shann (or Shan).
[2][3] They appeared twice at the Royal Albert Hall and toured with Cliff Richard, Adam Faith, and Morecambe & Wise.
Riss Long then formed the Chantelles with two friends, Sandra Orr and Jay Adams.
