The Stockholm Strings and Horns member was vacationing with his girlfriend in Thailand after completing the SMiLE tour in Australia and New Zealand. The two were at their hotel’s pool when the tsunami hit. Sandlund’s girlfriend was rescued but has not seen him since.

“I have been devastated since I heard the news that Markus is missing in Thailand,” Wilson said. “We have sent an agent to see what we can find out, but as of today we have been unable to locate Marcus in the area.

“If there is anyone out there who might know Markus’ whereabouts please contact [email protected]. My prayers go out to all of the victims and their families and I would ask you to say a prayer for Markus’ safe return.”
