The Hall of Fame - supported by British Airways and Heathrow Express - raised money for both Sport Relief and The Supporters Club and was hosted by Mark Durden-Smith and former Bath prop David Flatman.
Johnson, Baxter, Morrison, Chuter and Moody were present at the HAC, while Walkinshaw - who passed away in 2010 - was represented by his son Ryan, currently the majority shareholder at Gloucester Rugby and former Gloucester Managing Director, Ken Nottage.
"The six men represent a who's who of professional club rugby in England and we are delighted to welcome them into our Hall of Fame," said Phil Winstanley the Rugby Director at Premiership Rugby.
"In the list we have two Rugby World Cup winners, one of Aviva Premiership Rugby's leading coaches, a man who refereed a Rugby World Cup Final, a player who played more than 200 Premiership Rugby matches and a club owner who left an indelible mark on the game here in England. A formidable line-up.
"The Hall of Fame Dinner has become a significant date in the rugby calendar as it gives us a chance to look back on 18 years of professional rugby in England."
Michael Walker from Heathrow Express added: "We are delighted to be a partner of this spectacular evening celebrating Premiership Rugby."
The event raised funds for Sport Relief and The Supporters Club. As one of the UK's biggest fundraising events, Sport Relief brings the entire nation together to get active, raise cash and change lives.
"All the money raised by the public helps people living incredibly tough lives, both at home in the UK and across the world's poorest countries. Your support can help to make a dramatic difference to the lives of these people.
In 2013, Premiership Rugby's award winning social inclusion programme, HITZ, used Sport Relief cash to inspire communities through rugby.
