How to get post content from it's ID in multi site?

I’m running a multi site and I want to pull post with certain categories from two blogs. Therefore I am running a loop for each of the blog to pull the posts as one of the category is in blog 1 while the other category is in blog 2.

<?php $value = array(); ?>
        <?php
        		// Get the values from $_POST
        		$original_blog_id = get_current_blog_id(); // get current blog

        		$bids = array(1,2); // all the blog_id's to loop through  EDIT

        		foreach($bids as $bid):
             	switch_to_blog($bid); 

        		  $args = array(
        			'tax_query' => array(
        			'relation' => 'AND',
        				array(
        					'taxonomy' => 'Music',
        					'field' => 'slug',
        					'terms' => array('artist', 'club')
        				),
        					)
        				);

        		$the_query = new WP_Query( $args );

        ?>

        <?php $postids = array(); ?>

        <?php if ( $the_query->have_posts() ) { ?>

            <?php while ($the_query->have_posts()) : $the_query->the_post(); ?>

            	<?php $postids[]=get_the_ID(); ?>

            <?php endwhile; ?>

             <?php $value[] = $postids; ?>
        <?php
            } else {
                // no posts found
                echo 'Nothing found.';
            }  

        ?>
    <?php endforeach; ?>

    <?php 

    	$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($value));
    	$list = iterator_to_array($it,false);

    	$posts = new WP_Query(array(
    		'post__in' => $list,
    		'post_type' => 'post',
    		));

    ?>

    <?php
    	foreach ($posts as $post) {
        setup_postdata($post);
    ?>

    <?php echo the_title(); ?>
    <?php
    }

     wp_reset_postdata();     ?>

    <?php switch_to_blog($original_blog_id);  ?>

The reason why I’m getting the IDs inside an array:

<?php $postids[]=get_the_ID(); ?>

because I want to fetch random post’s. If at this point instead of the above statement I get the title and content of the posts then it will show in sequential order. Something like this:

BLOG1: POST1,POST2, POST : BLOG2: POST1, POST2, POST3

But I want Posts in random order like this:

BLOG1: POST1, BLOG2: POST3, BLOG1: POST2, BLOG2: POST1: BLOG2: POST2

So everything is working fine, I am able to get the posts IDs even outside the foreach loop but the problem is:

I am not able to get post content from those IDs. It only gives me posts from blog 2 because the current blog is 2. But it doesn’t show anything from blog1 even though the postID is in the list array.

Can anyone please help?
