A new T-Mobile advert has debuted on television featuring 13,000 people, but multimillion-selling singer Pink has also joined in the fun.
Sing-along is the name of the network’s new promo, following its Dance campaign which involved 350 people and an impromptu jive.
The ad was recorded in Trafalgar Square and premiered last Saturday (May 2nd) in the break of Britain’s Got Talent.
It sees thousands of participants pipe up and sing classic tunes such as Summer Nights from the musical Grease.
However, Pink – who is currently touring with her show Funhouse – also lent her vocals to the clip.
"Everyone singing along together in the middle of London," she said. "It was incredible! I was thrilled to be a part of such an amazing event and to share it with so many people."
Current handsets available from T-Mobile include the G1, which is one of the latest phones that could tempt people who want to equip themselves with a better gadget.
