The tribute to his friends came as Surrey police revealed the identities of three more of the men who died in the road smash, which occurred after the recovery vehicle they were travelling in collided with a lorry between junction eight and nine of the motorway in the early hours of the bank holiday.
Brighton residents Andrew Graney, 29, Jonathan Chandler, 23, and doctor Matthew O’Donnell, 30, all died in the collision.
Police earlier confirmed that another Brighton medic, Christopher Janaway, 28, was among those killed as the stag party made their way home from Leicestershire in the cab of the breakdown van after the minibus they had been driving broke down on the M1.
Detectives have yet to formerly identify a fifth member of the stag group and the driver of the recovery vehicle, who also lost their lives in the incident.
The driver of the HGV vehicle was unharmed in the crash.
Paying tribute to the dead men yesterday, saddened bridegroom Mr Forrer said that the accident had "ended the lives of five beautiful friends".
"Coming to terms with a loss of such magnitude will require much time and energy and the warmth and love of all of the families and friends involved," he added, stressing that everyone who knew the deceased were "inconsolable".
"I'm so grateful that we were all able to share a terrific weekend’s celebration that was filled with laughter," Mr Forrer reflected.
Surrey police have confirmed that its collision investigation unit is examining the events of the crash, but has warned that it could take "days if not weeks" before they are able to report on the progress of their enquiries.
