Add text before $title in posts

Hello,
I have renamed a copy of single.php to use for some specific posts. The php template is untouched, from memory, it was just done so as not to interfere with other posts in future. The actual content (but evidenty not the post title) is all in another php template. The post title shows up at the top of the page as h1 text, which is okay, but I cannot see how to customise it.

Let’s say that I have two posts in this category, one called “British Bulldogs” and another called “French poodles”.
I want to be able to add a standard block of text that runs inline with the post titles; let’s say the text will be “Mickey Mouse loves “.
The idea is I get H1 titles saying “Mickey Mouse loves British Bulldogs” and “Mickey Mouse loves French Poodles” and so on.

How do I do that? I tried manually inserting text all over the place and all it did was break everything!
Any help appreciated.

Brian
