Tom Jones eat yer heart out. Love the bluegrass feel on the track, and Beepster's vocal is perfect for it.
Gotta' throw in with Frank on the silliness part. Yeah, it's cute and all, but I think the comical lyrics distract the listener from what otherwise would have been a really well done and fresh off-genre take on a big pop ballad. Next time you have an approach this clever, play it straight (i.e.- lyrically).
All told though, a great job by all.
