Top of the Pops, 26th March 2015

A bit of TOTP musical chairs this week produces some special one-offs. Bruno Mars is out of town so Mark Ronson calls on Olly Murs AND Maroon 5's Adam Levine to bring their song and dance man talents to Uptown Funk. Murs in turn recruits Sam Smith for the Lovato role on Up, before returning the favour to do justice to John Legend's lines on still-number-one Lay Me Down.

We also see James Bay scale a new chart peak, and a trio of dance hits rounds out the show.

Debut: Tough Love.

Maroon 5 - Sugar

Up 1 to number 10

Mark Ronson ft. Olly Murs and Adam Levine - Uptown Funk

Up 1 to number 8

James Bay - Hold Back The River

High Climber - Up 6 to number 4

Top of the Pops, 12th March 2015

Tons of new entries this week and not many climbers in the upper reaches, so we have room for a presumable future hit from Calvin Harris and Haim and a once again resurgent Imagine Dragons, among other varied delights.

Queen Taylor favours us with a visit, but she can't go on for too long because Kanye West is also here and he has two current hits to fit in. Anyway the week belongs to Years and Years as King receives its coronation.

Debuts: Alex Adair, Marlon Roudette.

Alex Adair - Make Me Feel Better

In at number 13

Marlon Roudette - When The Beat Drops Out

In at number 7

Imagine Dragons - Demons

High Climber - Up 27 to number 33

Calvin Harris ft. Haim - Pray to God

Up 11 to number 46

Lilly Wood - Prayer in C

Up 2 to number 50

Taylor Swift - Style

Up 6 to number 22

Kanye West - All Day / FourFiveSeconds

In at number 18 / Up 2 to number 3
