We had the same type of music when I was growing up.
Here is a quick tutorial for posting YouTube videos:
First, hit the 'new reply' button and ignore/don't use the quick reply window.
Next, just above you'll see a "YouTube" icon up above and to your right (second icon from the right).
Click it and type in "Sacred Heart" (or any title you like, doesn't matter) and click "ok"
Next copy the last part of your link after the equal sign
http://www.youtube.com/watch?v=G2Ejipe3rVE
- "G2Ejipe3rVE" in this case from your link.
Paste it between the ] G2Ejipe3rVE [ marks that will pop up.
{YT="Sacred Heart"]G2Ejipe3rVE[/YT}
It'll look close to this but with [ ] braces instead of { } these
Hit submit
