Display both post title and page title

Hello everyone,

I have a WP page where I’m pulling a specific post in and displaying it. In the <title> I would like to display post title followed by the page title.

I have the following code:

if (is_single()) {single_post_title(); echo " - "; wp_title(); echo " - "; bloginfo('name');}

The single_post_title() – displays the title of my post (that’s great), but I was hoping wp_title() would display the page title, but instead it displays post title again.

Is there a way to display both – post title and page title with such set up??

Would really appreciate any help.
Thanks,
Dasha
