Postal Service fans encouraged by the appearance of its John Lennon cover ('Grow Old With Me') on 2007's star-studded 'Instant Karma: The Amnesty International Campaign to Save Darfur' shouldn't get their hopes up about a follow-up to 2003's 'Give Up.'

With Death Cab for Cutie's 'Narrow Stairs' on the horizon (May 13, to be exact), the opportunity to ask frontman Ben Gibbard -- who partners with Dntel's Jimmy Tamborello in the Postal Service -- about the future of the electronic pop duo presented itself.

"It's just not a priority for either of us," Gibbard tells Spinner. "So the next Postal Service record may or may never happen." In 2006, the pair reportedly started work on a follow-up to 'Give Up,' which is the second best-selling album in the Sub Pop catalog behind Nirvana's 'Bleach,' but things have yet to take shape.

"Jimmy and I are still throwing ideas back and forth, but as time goes on, we find ourselves busy with our own music," Gibbard continues. "We have some stuff, but it's been difficult to find the time and the drive to do the record. I'd love to finish it at some point and maybe even do some performances. If it's meant to be, it's meant to be."
