Best Morrissey tattoo I've ever seen, hands down, was olde English text, no picture, the words: 'long may it last'.
Your idea sounds very nice, slimjim.

If you want your Moz tattoo to also proclaim your love for your wife, there aren't many statements of devotion that don't also come with an ironic tone or some kind of caveat... and, no offense to anybody who's got one (except for Pete Wentz - screw him), but there are far too many 'there is a light that never goes out' tattooes out there already. Haven't seen very many 'now my heart is full's.
