Hi Krishnanand,

The demo content for free version theme is not available. The Music Club PRO theme comes with XML file of demo data.

To customize this free theme, first create all pages for slider, services and welcome section with Featured Image
Then Go to the Appearance -> Customize -> Theme Options Panel -> Slider/services/welcome -> Select Page
Please check the documentation to customize the Music Club Lite free theme
