This does the first three quotes, it should be obvious enough how to add the rest.
$quotes = array("Spirits flying through the air<br>Crossing over to the other side<br>To rest in peace and never die again<br><br>And to be with long gone friends",
"In the misty morning, on the edge of time<br>Weíve lost the rising sun, a final sign<br>As the misty morning rolls away to die<br><br>Reaching for the stars, we blind the sky",
"Where the hell have I been<br>Sleeping, lost, and numb<br>So glad that I have found you<br><br>I am wide awake and heading home"
