TV tonight: who were the original singers of pop’s biggest bangers?

40 Originals at the BBC

8.20pm, BBC Two

Get comfy for a big one: more than two hours of pop hits performed by the original artists. Take Status Quo’s Rockin’ All Over the World, which was actually first recorded by John Fogerty in 1975. Or Killing Me Softly, which was penned by Lori Lieberman before Roberta Flack made it a global hit. Other treasures of the night include Gladys Knight, LaBelle, Nine Inch Nails, Dolly Parton and the Zutons. Hollie Richardson

Gladiators

5.50pm, BBC One

The Travelator has caused the downfall of many a promising contender – and the semi-finalists must conquer it to secure a place in the final. Meanwhile, Legend and Viper let their emotions get the better of them, but even an arena scrap can’t overshadow a record-breaking performance on the Eliminator. Ellen E Jones

Ancient Greece By Train With Alice Roberts

8.10pm, Channel 4

Prof Roberts is on the island of Paros, so it’s more by foot and boat than by train. Paros has numerous sites of deep archaeological interest, while a hop across the water to Delos brings us to where the Temple of Apollo once stood. From there to Turkey, where Greek culture once held sway. Jack Seale

Portugal With Michael Portillo

8.15pm, Channel 5

The roving ex-MP sets course for Sintra, a medieval timewarp on the way to Portugal’s west coast. After a hair-raising tour in a tuk-tuk, he chows down on local sweet treats, bonds with a laid-back surfing guru and keeps an admirably straight face at a healing retreat when asked to “blow an intention” into some hot cocoa.
