There's Nothing Holdin' Me Back Shawn Mendes
Glee returned to our screens on Monday evening and as always, that means we can expect to see songs from the show on Sunday's Big Top 40.
The best performing song from the first episode of season 2 of the hit US show is Rachel and Sunshine's cover of Lady Gaga's hit with Beyonce, 'Telephone'.
By Tuesday evening, 'Telephone' was already in the live iTunes top 10 and looking like it would score a place in Sunday's chart.
Other performances which could end getting a play in the Big Top 40 on Sunday are New Direction's version of Jay-Z and Alicia's 'Empire State of Mind' and Travie McCoy's 'Billionaire' - both of which are already in the top 20 on iTunes.
Make sure you're listening to the Vodafone Freebees Big Top 40 with Rich + Kat this Sunday from 4pm, they'll let you know first where the Glee Cast end up in our chart.
Next Monday night a Britney Spears special will air in the UK, so look out for covers some Britney classics in next week's chart including 'Toxic' and 'Baby One More Time'.
