Betcha Bottom Dollar is the debut studio album by the close harmony trio The Puppini Sisters, released through Universal Classics and Jazz on 31 July 2006 in the United Kingdom.

"[2] Tom Lewis from Universal Classics and Jazz signed The Puppini Sisters to the label after seeing them perform live at Trinity College of Music in London, where the girls had met.

"[5] Betcha Bottom Dollar mixes traditional close harmony songs, like "Mr. Sandman", with more modern tracks like Kate Bush's "Wuthering Heights".

Heather Phares from AllMusic stated "Taken individually, the trio's voices aren't spectacular, but they blend together nicely enough to create a convincing homage to the heyday of vocal harmony pop in the '30s and '40s.

Sandman,' a pretty, languid 'Java Jive' and 'Sway' are among the best vocal pop standards on Betcha Bottom Dollar, but interestingly enough, the Puppini Sisters often sound less campy on the songs they remake than on the classics.

"[1] The Guardian's Maddy Costa gave the album a less positive review, commenting "The singing is charmingly cute throughout, but that's it: perfect for the Chordettes' track 'Mr Sandman', and surprisingly effective in a cover of Kate Bush's 'Wuthering Heights', but less comfortable in 'Falling in Love Again' (oh!

[7] Helen Brown, writing for The Daily Telegraph proclaimed "The covers of modern songs, such as the Smiths' 'Panic' and three close-harmony Cathys on Kate Bush's 'Wuthering Heights', will appeal to art-school ironists.

[6] Andrew Eaton from The Scotsman said "the skill and effort that's gone into the brisk, light-as-a-feather arrangements is very impressive, even if the joke wears thin as quickly as with any other novelty cover versions".
