Tamla Motown European revue March/April 1965 - a question

[blue_whippet]

I wonder if anyone can help with this question and satisfy my curiosity. What dates did the review appear in Rotterdam and Hamburg [[Supremes only perhaps?) The UK dates of the review are well publicised and it is known that the review ended in Paris on April 13th. Even though a photo of the review on stage in Rotterdam has appeared on this forum and several photos of the Supremes in Hamburg can be found on the internet, it is difficult to determine at what stage of the visit they appeared in Holland and Germany. Could these appearances have occurred before they started the UK leg or could they have happened during the UK tour on days off? It seems strange that these parts of the tour are hardly ever referred to in any literature on the subject. Any help would be most appreciated. Thanks.
