We've been hearing about — and highly anticipating — a Glee tribute episode for the late, great Whitney Houston for some time now, and based on the sneak peek that was unveiled on Thursday, the episode might be a must-see-and-hear even for the show's biggest detractors ... like yours truly.

In the moving clip, Mercedes (Amber Riley), Santana (Naya Rivera), Kurt (Chris Colfer) and finally Rachel (Lea Michele) perform a rendition of Houston's hit song, ""How Will I Know,"" and the results are genuinely difficult not to appreciate.

Take a look at, and a listen to, the preview, below — and don't miss the episode itself, fittingly titled ""Dance with Somebody,"" when it airs April 24.
