In 1956, singer and political activist, Paul Robeson was banned from travelling outside of the USA, due to McCarthyism. When testifying at HUAC he claimed his 5th Amendment rights, and refused to reveal his political affiliations. Consequently, his movements were restricted.
The following year, to get around this ban, Robeson performed his first Telephone Concert, where he entertained 1,000 concert goers in London, from his base in the USA.
