At the request of the Boston family, people attending are being encouraged to wear traditional funeral attire, but items of Wigan Warriors’ cherry red can be worn such as scarves, ties and headwear.
People are welcome to pay their respects to the funeral cortege, which will follow a route through Wigan.
Born in Cardiff in 1934, Boston grew up playing union but was overlooked by his home club. He came to the attention of rugby league scouts while on national service in the north of England, signing for Wigan in 1953 as a 19-year-old.
He was picked for the 1954 Great Britain side and was the first black British player to tour Australia and New Zealand.
He reached the 100-try milestone in just 68 matches and claimed 478 tries in 488 games for Wigan, helping them win three Challenge Cups and the Championship.
In all, Boston scored 571 tries in his career – a total surpassed only by Australian legend Brian Bevan in top-class rugby league – and is one of the truly great British rugby league players.
