but the problems is, Google shows my old content when i type site:mywebtheatre.com in the search box, it is showing the old music contents only. i want to remove those from google sepr.

can you help me.

 

You need to wait. Google will do it automatically. As I know you can`t do anything.

 

I think you should wait till google bot crawl your site's new content.

 

you can do link building, so Google will crawl your site faster and make the changes in SERP. You yourself can not change it.

 

I think it MIGHT help to remove then in webmaster tools. Google will then check if they are blocked through robot or noindex, and if not, they might try to fetch the newest version? Just a theory, guess the best it to wait and see.

 

Just Update your website with new content...
Update your sitemap periodically and submit to Google.

Google will automatically fetch new version, however it takes little time to show the correct version in Site Attribute.

 

Yes, the regular updates and improvements in quality always help!

 

You can also go to google webmaster tools to set the robot.txt to stop crawling specific page. 
