Brake title in two parts and comments problem in Wordpress

Custom title for wordpress posts which i can use in a link. Example We have the title of the post: Rihanna - We Found Love Song I need a code that will brake this title in two parts : - first part (the one before the dash) is the name of the artist -second part (the one after the dash) is the name of the song And also remove the last word (which in this case is always "song" ) Example of a link: <a href="http://www.otherdomain.com/&artist=NAME OF THE ARTIST&song=NAME OF THE SONG"> </a> IMPORTANT note I only need the code for this link (which will be added on my theme), the actual title of the post has nothing to do with this, it will remain the same, you don't have to change anything. And i also have a problem with the comments on my current theme. If there is more than one comment in a post, the footer and the sidebar won't load.
