A bride and groom were stunned when their guests broke out into a "Stand by Me" performance. Neither of them had any idea what was happening or why. Watch the short but sweet clip to hear the wedding guests sing "Stand by Me" and see the shocked expressions from the bride and groom.

Weddings are beautiful, life-changing ceremonies. They are the joining together of two people who vow to remain with one another for the rest of their lives, regardless of what life may throw at them. The moments and memories created on a couple's wedding day will be remembered and looked back upon fondly for years to come. What could be more beautiful than a wedding?

In addition to being beautiful and emotional ceremonies, weddings are often very organized, thoroughly planned and thought-out. Typically, every possible detail and item is meticulously and carefully accounted for and considered. That's why couples will allow for a year's gap between getting engaged and getting married. They want every detail to be perfect for their big day, and why not? Weddings are important and should be given the care and thought they deserve.

However, a clip posted on YouTube shows a special, heartwarming moment that neither the bride nor the groom had planned. In the video, the bride and groom sit at the front of the room when someone unexpectedly stands up and begins singing. The look on the couple's faces made it abundantly clear that neither of them had the slightest clue about what was happening. But they both went with it, letting the moment happen.

Then, slowly, more guests stood and joined in on the performance. Soon, a handful of guests were singing the beautiful, timeless love song "Stand by Me."

That is a moment they will remember for the rest of their lives.
