Speed's parents Roger and Carol and sons Ed and Tommy were joined on the pitch by close friends Alan Shearer, Steve Harper and John Carver.
Alan Pardew: "It was a chance for the Geordie folk to show their respect for Gary and their love for him, and they did that in a really magical way.
"It was hairs on the back of your neck stuff there, and I am sure his family were very, very pleased and happy with that."
Welsh tenor Gwyn Hughes Jones led the crowd in a rendition of the hymn Bread of Heaven in a tribute which was also appreciated by the Swansea contingent.
Swansea boss Brendan Rodgers: "Roger and his family will never forget that. It was a lovely touch by Newcastle and congratulations to them."
