Train was petitioned by soldier Jonathan Tremblay to help him propose to his fiance while they where having lunch.

The band played their famous tune 'Marry Me' but the funniest part is that his fiance is totally clueless that he is getting ready to propose!

How freaking romantic! Do you think he can get them to play at the wedding too? Congratulations to the Happy Engaged Couple! Rock on Train!
