Short answers, pulled from the story.
The Roy Orbison/The Beatles Tour began on the 18th of May 1963 in Slough and concluded on the 9th of June 1963 in Blackburn. This schedule covered venues across England, Wales, and Scotland over a period spanning three weeks.
Other acts on the bill included Gerry and the Pacemakers, David MacBeth, Louise Cordet, Tony Marsh, Terry Young Six, Erkey Grant, and Ian Crawford. These performers shared the stage with the two main headliners during the tour dates.
Crowds responded with overwhelming enthusiasm to The Beatles which forced promoters to adjust the schedule so that The Beatles closed the set in the traditional headlining spot. By mid-tour both acts shared co-headliner status rather than maintaining a strict hierarchy.
Roy Orbison delivered his own set featuring Only the Lonely Candy Man Running Scared What'd I Say Dream Baby and In Dreams. These performances highlighted his distinct style alongside the other acts throughout May and June 1963.
The final show occurred in Blackburn at King George's Hall on the 9th of June 1963. This venue marked the end of the tour after stops across England Wales and Scotland.
