Olly Murs has left fans feeling overwhelmed after sharing a compilation of old clips from when he presented The X Factor with his late pal Caroline Flack.The pair hosted the The Xtra Factor between 2011 and 2012 before going on to host the main show as a duo until 2015. What made their appearances so memorable though was their hilarious dance entrances to the beat of popular songs such as Abba's Dancing Queen and Michael Jackson's Black Or White.
