Albert Bonici managed to book The Dave Clark Five for five gigs in Scotland just as they were about to go global. However, they didn’t perform in Scotland in June, 1964 as was agreed. They toured the USA instead according to tour dates 1964 http://www.thedc5.com/diary.html
“The Dave Clark Five (also known as “The DC5”) were an English pop rock group. Their single “Glad All Over” knocked the Beatles’ “I Want to Hold Your Hand” off the top of the UK singles charts in January 1964: it peaked at number 6 in the United States in April 1964.
They were the second group of the British Invasion on The Ed Sullivan Show, appearing in March for two weeks after the Beatles appeared three straight weeks in February 1964. For some time the Dave Clark Five were more popular in the US than in their native UK, but had a renaissance in the UK between 1967 and 1970.” http://en.wikipedia.org/wiki/The_Dave_Clark_Five
