The Flash: 10 Things You Didn't Know About Grant Gustin
8. One Of His Most Famous Glee Performances Was Actually A Deleted Scene
When fans of The Flash find themselves looking up some of Gustin's best Glee performances online, they often come across his awesome rendition of Jackson 5's classic 'I Want You Back'.
With the Dalton Academy Warblers backing him up, Sebastian dances his heart out as Gustin's smooth vocals revitalise the catchy song in a moment that understandably intimidated the show's primary Glee club. Unfortunately, this scene never actually made it to air.
It was due to feature in the show's Michael Jackson tribute episode - which took place during its third season - but timing restrictions meant that it was sadly left on the cutting room floor. But alas, it was resurrected when Glee co-creator Ryan Murphy uploaded it online where it has, as of writing, amassed a staggering 34 million views.
