The Wanted's 'Glad You Came' Covered By Glee Cast - Video
The 'Warzone' singers' 2011 Big Top 40 number one has been covered on the latest episode of FOX's Glee.
Earlier this month the 'Lightning' singers confirmed that the track would be covered by the cast of the hit FOX series, following the success of The Wanted's first US tour at the start of February.
'Glad You Came' was covered in the Glee episode 'On My Way', which aired on FOX yesterday, when the song was performed by Grant Gustin's character Sebastian Smythe alongside Glee club rivals The Warblers.
"Big thanks to @gleeonfox for featuring #GLADYOUCAME & a huge thanks to all our fans for supporting us and getting #TheWantedOnGlee to trend," The Wanted tweeted yesterday.
The official YouTube video clip of the Glee cast's 'Glad You Came' performance has already racked up over one million views since being posted last night.
The Wanted are currently in the middle of their UK arena tour 'The Code' and are next due to perform tomorrow (23rd February) at the Cardiff Motorpoint Arena.
