LONDON, Nov 3 — Bruno Mars put his own spin on the Adele song All I Ask for BBC Radio 1 and BBC Radio 1Xtra, a song he co-wrote with the British singer.

Mars gave the song an old-school R&B's vibe, a different take from the classic torch song mood of the original.

What's even more impressive? The key change midway through the song, which showcases just how huge a range Mars has.

A note to fans: Mars has a new album out, 24K Magic, which you can check out in record stores now.
