Introduction of Candidates? What Candidate? This isn't the Order of the Arrow - its a Court of Honor to formally present to an Eagle Scout the awards he's already earned - he isn't a candidate - he's an Eagle Scout.
My best friend had his Eagle Scout ceremony in 1978 - his Troop put together the ceremony using the suggestions from NESA (It was scheduled a couple of months in advance so that his grandparents from England could come to the ceremony). They did an Eagle Charge and an Eagle Pledge. The ceremony took place in a church and took about an hour. At least the Troop paid for the ceremony and simple reception afterwards.
My ceremony was in 1979. It took place at a regularly scheduled Court of Honor of my Explorer Post's sister Troop (at the time, I was no longer a member of the Troop - I left the Troop when I was 16 in favor of my Post - I had to give one of them up and the Post was more of what I was looking for - most of the members of the Post were current or former members of the Troop anyway) - I earned my Eagle Scout as an Explorer Scout - within my Post - but my brothers were still involved in the Troop and we did some activities together. At the end of the Troop's awards, the SPL turned the ceremony over to the President of my Post. He called for an Eagle Scout to escort me to the front - my best friend, who was neither part of my Troop or Post, did the honors. After introducing me, the President asked that my parents be escorted up - they were brought up by my younger brothers who were in the Troop. The Pres invited my former Scoutmaster up (the one I grew up in the Troop with) to tell a story - he, of course, had to go with the story of waking up to see a fox sitting on my chest licking the salt off my forehead on a backpacking trip in Isle Royale. Then my Post Advisor was called up to give my parents their "parent pins" and to give my mother the medal to pin to my shirt. That was it - took less than 10 minutes. There was no Eagle Charge, no Eagle Pledge, no long recitations of letters or congratulations - no fancy candle lighting ceremony - just congratulations and handshakes and hugs all around. My best friend told me he wished his ceremony could have been that simple.
