"Girls" is the unmixed single version (same as on "Girls" single). Version of "Memphis Bells" is different to the album version and is exclusive to this release - it's an instrumental version, without the Princess Superstar vocals. Durations same as promo CD release.
From old XL Recordings site:
"Taken from their new album 'Always Outnumbered, Never Outgunned' due in August. This is an album sampler, and available in VERY limited quantities. Order now, to avoid missing out!!"
