Keith, managing director at Sutton-based KG Express, has built up quite a social media following since last year when he started posting videos of himself and others singing from his delivery van.

And he has more recently taken to creating versions of songs with Saints-based lyrics.

These have included a version of Mambo No. 5 with lyrics based around winger Regan Grace, called Regan No 5 and a catchy tongue-twisting version of electronic group The Shamen's 1992 hit Ebeneezer Goode which is dedicated to Saints' other winger Tommy Makinson.

Keith has followed that up with others including a rendition of Here Comes The Hotstepper, by Ini Kamoze, with lyrics based on Saints' Fijian international centre Kevin Naiqama, while one is dedicated to Dom Peyroux and another to Justin Holbrook.

Keith is looking to do a massive recording of some Saints-themed songs on Saturday. These will include Regan No 5, the Dom Peyroux song and You Light Up My Senses (Annie's Song).

""I am inviting people down if they want to take part in a massive Live Lounge, it's going to be a big one!" said Keith, 45.

"I have gone to the Green Man for every Wembley trip, it is only four or five minutes from the stadium.

"It will be nice to meet people who have taken the time out to watch my videos.

"I love the feedback they've had, it's really positive and everybody buzzes off it. It has done exactly what it is supposed to do.

"I never thought it would go past Sutton and it has made it to the other side of the world.

"The Gold Coast Titans did a version of it and it was on an Australian news channel."
