Cakephp joining tables via find option not working - php

Question

I'm trying to join a Users table to my curent hasMany Through table which has Interest and User model id's.
Below is the find query with options:
$params = array(
'fields' => array('*', 'COUNT(DISTINCT(InterestsUser.interest_id)) as interest_count'),
'limit' => 15,
'recursive' => -1,
'offset' => $offset,
'conditions' => array('InterestsUser.interest_id' => $conditions),
'group' => array('InterestsUser.user_id'),
'order' => array('interest_count DESC', 'InterestsUser.user_id ASC', 'InterestsUser.interest_id ASC'),
'joins' => array(
array('table' => 'users',
'alias' => 'User',
'type' => 'LEFT',
'conditions' => array(
'User.id' => 'InterestsUser.user_id',
)
)
)
);
$results = $this->InterestsUser->find('all', $params);
This returns InterestsUser table fine but does not return any values for Users table. It only returns field names.
What could be wrong?
UPDATE:
OK, above is generating below SQL which I got from Cake's datasources sql log:
SELECT *, COUNT(DISTINCT(InterestsUser.interest_id)) as interest_count
FROM `interests_users` AS `InterestsUser`
LEFT JOIN users AS `User` ON (`User`.`id` = 'InterestsUser.user_id')
WHERE `InterestsUser`.`interest_id` IN (3, 2, 1)
GROUP BY `InterestsUser`.`user_id`
ORDER BY `interest_count` DESC, `InterestsUser`.`user_id` ASC, `InterestsUser`.`interest_id` ASC
LIMIT 15
Why is users table values returning NULL only for all fields?
UPDATE:
OK I tried below but this is working fine...What am I missing here!!??
SELECT * , COUNT( DISTINCT (
interests_users.interest_id
) ) AS interest_count
FROM interests_users
LEFT JOIN users ON ( users.id = interests_users.user_id )
WHERE interests_users.interest_id
IN ( 1, 2, 3 )
GROUP BY interests_users.user_id
ORDER BY interest_count DESC
LIMIT 15

The array syntax for join conditions should be like the following
array('User.id = InterestsUser.user_id')
as opposed to array('User.id' => 'InterestsUser.user_id'). For more, see http://book.cakephp.org/view/1047/Joining-tables.
