Come on now let's open fire

The story:

My 5 yo was going around the house singing, "Come on now, let's open fire," and I asked him what he was doing. He told me he'd heard this song on Dad's radio. It took me a bit (his melody was a bit off) but I finally figured out it was the Doors', "Come on, baby, light my fire" he was singing. "Oh," I said, "You have the wrong lyrics." "What does the song really say?" he asked. I realized I did not need him singing the real lyrics. "Actually," I said, "Your lyrics are better," and for years he continued to sing those lyrics.
