Oh fixed it myself. I’ve added the following into single-event.php, which includes day date month, time on a separate line, and a book now button
<div class="tribe-events-schedule tribe-clearfix">
<h2><?php echo tribe_get_start_date ( null, false, 'l j F' ) ?></h2>
<h2><?php echo tribe_get_start_time(); ?> - <?php echo tribe_get_end_time(); ?></h2>
<?php if ( tribe_get_cost() ) : ?>
<h2><span class="tribe-events-cost"><?php echo tribe_get_cost( null, true ) ?></span></h2>
<?php endif; ?>
<div class="button photo-view-button"><a class="tribe-event-url" href="<?php echo esc_url( tribe_get_event_link() ); echo "?tickets_process=#buy-tickets" ?>" title="<?php the_title() ?>" rel="bookmark">book now</a></div>
</div>
