American academics have lashed out at English rugby fans for their use of the black slave anthem "Swing Low, Sweet Chariot".
The song was first adopted by rugby crowds in 1988, after England completed an impressive comeback victory over Ireland.
On that day, Chris Oti - the first black player to represent England for 80 years - scored three tries.
But the refrain is believed to have origins in the 19th century, where it is believed to refer to the secret Underground Railroad movement that helped slaves escape from captivity into free states and Canada.
It was rekindled during the US Civil Rights movements of the 1960s and has been covered by various artists over the years, including a stirring performance by Joan Baez at the legendary 1969 Woodstock festival.
