I used a auto generated HTML code from Songkick and I put it straight into the HTML on my Tumblr website and its not showing anything but the title. You can look at it here http://yuniwamusic.com/shows
This is the code I used
<a href="http://www.songkick.com/artists/8434448" class="songkick-widget" data-theme="light" data-track-button="on" data-detect-style="true" data-background-color="transparent">Yuni Wa tour dates</a>
