Lord Mayor's show

While watching the Lord Mayor's Show in London , we wondered if our ancestor took part in such a show in Exeter.
As our ancestor in 1911 Charles James Vlieland was a lord Mayor there.
In Exeters Mayors It is stated that:-Charles James Vlieland was a Doctor who lived in West Southernhay. During his time as Mayor, he opened.Rougemont Gardens for the public. Charles Vlieland's grandfather was Dutch and he has living relatives in the Netherlands.
