"A video of the Glee cast singing Whitney Houston&amp;#039;s &amp;#039;How Will I Know&amp;#039; has been released online.  The late musician&amp;#039;s track is given an acapella reworking by Mercedes (Amber Riley), Rachel (Lea Michele), Kurt (Chris Colfer) and Santana (Naya Rivera).       The clip is taken from next week&amp;#039;s tribute episode &amp;#039;Dance With Somebody&amp;#039;, which also features Houston&amp;#039;s songs &amp;#039;Saving All My Love For You&amp;#039;, &amp;#039;My Love Is Your Love&amp;#039; and &amp;#039;I Have Nothing&amp;#039;.  A Glee insider has said that the episode will &amp;quot;not be a typical tribute&amp;quot;, explaining: &amp;quot;It&amp;#039;s using Whitney&amp;#039;s music as a way to say goodbye. A way to respectfully say thank you for her music.&amp;quot; Riley covered Houston&amp;#039;s famous ballad &amp;#039;I Will Always Love You&amp;#039; in an episode that coincidentally aired just three days after the music icon&amp;#039;s death on February 11.  Glee&amp;#039;s tribute to Houston will air Tuesday at 8/7c on Fox in the US and Thursday at 9pm on Sky1 in the UK.  &amp;gt; &amp;#039;Glee&amp;#039; Amber Riley on Whitney Houston: &amp;#039;Her acknowledgment was enough&amp;#039; "^^<http://www.w3.org/2001/XMLSchema#string>
