A former freemason found drunk and naked inside a huge pipe organ has appeared in court accused of damaging the historic instrument - insured for more than $1 million.

Glenn Langford was arrested on Wednesday after allegedly flooding the Brisbane Masonic Memorial Centre and setting off the fire alarms.

The 51-year-old faced charges at the Brisbane Arrest Court on Thursday and was granted bail.

But he said his intentions were initially well-meaning and the night had got out of hand after downing a bottle of Johnny Walker whisky, 7 News reports.

The court was told he had been meaning to hand out cheeseburgers to the homeless.

Food was left scattered on the floor of the grand hall of the heritage-listed temple in Brisbane's CBD, which features one of the biggest organs in Queensland.

It is feared the organ, installed in the 1930s, may be too damaged to be repaired despite it being insured for $1 million.

Mr Langford is charged with allegedly damaging a number of organ pipes and destroying part of a decorative wall.

He was also discovered naked along with clothes, a remote controlled police car and toy gun.

The magistrate heard from Mr Langford's lawyer who explained he had last week lost his job and was getting over the breakdown of a 16-year relationship.

Decorative wall was reported to be damaged and the pipes were also allegedly damaged overnight

He was granted bail on the condition that he stayed more than 100 metres away from the centre in Ann Street.

'Things just got a little loose, I was out of it,' Mr Langford told 7 News.

He apologised to 'all the righteous Freemasons everywhere'.

'I did have a lot of cheeseburgers to give to the homeless. I'm going to see a shrink and don't drink,' he added.
