Wasn't thrilled about "Pretty mouth" but I like "Clementine".
I feel, however, that the guitar and vocal on both are good, just right. I'm probably a lousy judge on the recording aspects of a song; I often marvel at the comments about frequencies and scooped mids and woofy kicks and stuff because I just can't hear any of that ! I gauge songs on whether or not I like them and generally, I'm happy to accept what the artist presents. Even if I was able to think of changes that I'd make, whether they'd actually be an improvement is something only a brave bookie would take bets on.
I would never have known that mismatched mics were used or anything like that. On 'Clementine' I particularly like the guitar and the melody. It reminds me of Melanie in her quietly intense moments (like "The Citiest people").
