Sports Illustrated's annual swimsuit issue is out featuring Kate Upton on the cover and now a trailer has been released for the issue and its soundtrack is set to Train's latest hit "Mermaid".

The band's song was chosen for the soundtrack but Train themselves didn't get to tag along with the SI cameras as they went across seven continents to photograph the swimsuit models in their bikini's in the snow, the desert, on rocks, in the river and of course on the beach too!

The video follows right along with the song lyrics. Train is set to kick off their Mermaids of Alcatraz tour in July and will be at the Gexa Energy Pavilion in Dallas on Saturday, August 3rd.
