[2] Sealey celebrated getting married in May 1965 just one week before he would go on to score both goals in West Ham's 2–0 win against TSV 1860 Munich in the 1965 European Cup Winners' Cup final at Wembley Stadium.

[3] He had previously scored just three goals for the east London club that season.

He was playing cricket with teammates during a rest in pre-season training, and broke his leg while falling over a wooden bench.

[4] His family maintained its close connection to West Ham United, with his nephew, Les,[5] and grand-nephews signing for the team between 1994 and 2001.

Sealey died suddenly at his home in Collier Row, Romford in February 1996 from a heart attack,[5] aged 53, just over five years before the same condition would claim the life of his nephew, Les at age 43.
