Question

Is it possible to use the loop in order to query a specific post and display that posts content, title and custom fields on my page?

i was thinking something like:

if (have_posts() && the_post().id == 66) : while (have_posts()) : the_post();

It sounds like you need to use query_posts() where p = the post_id (1)

<?php query_posts('p=1'); ?> 
<?php while (have_posts()) : the_post(); ?>
     <?php the_title(); ?>
     <?php the_content(); ?>
<?php endwhile; ?>
