This weekend's must-watch TV was a no-brainer - and best of all, the One World: Together at Home concert delivered as promised. Curated by Lady Gaga, it's best thought of as a spiritual successor to Live Aid, featuring a similarly jaw-dropping line-up of mega-stars all trying to raise money for a good cause - in the case of 2020, that being the WHO and coronavirus frontline workers around the globe. Read on for how to watch the One World: Together at Home concert on TV or stream it for free online wherever you are this weekend.

One World: Together at Home UK time One World: Together at Home is an unprecedented virtual event organized to raise funds for the WHO and frontline healthcare workers during the Covid-19 pandemic. With a line-up handpicked by Lady Gaga, the live two-hour mega show took place on Saturday April 18 in the US - or early Sunday morning in the UK. It's available to watch and re-watch pretty much anywhere with internet access, but cord-cutters had it best courtesy of Sling TV, which allowed anyone to stream One World: Together at Home for free. In the UK, the BBC is airing in Sunday, April 19 at 7.15pm.

Gaga dubbed the event "a love letter to the world" and some of our highlights included (minor spoiler alert?) Jennifer Hudson's breathtaking rendition of Hallelujah - a stunning cover of the classic Leonard Cohen song that's right up there with the Jeff Buckley version. Paul McCartney certainly looked like he was having fun, too, even if there was a hint of student union karaoke about his performance. Elton John, on the other hand, positively rolled back the years and was in vintage form.

Other major takeaways from the night? Celebrities have really nice houses to self-isolate in, you definitely don't want to play a drinking game involving the word 'unprecedented' any time soon, and Eddie Vedder's voice is one of the wonders of the modern world.

While it has now aired live in the US, you can still easily watch One World: Together at Home online if you missed it- and those in the UK have the official BBC broadcast to look forward to tonight at 7.15pm BST.

One World: Together at Home - UK time and lineup highlights

This weekend's blockbuster gig was hosted by Jimmy Kimmel, Jimmy Fallon and Stephen Colbert - but they're almost an afterthought compared to the One World: Together at Home lineup, which reads like a festival organizer's dream.

Jackson; and three of biggest acts of 2020 in event curator Lady Gaga, Billie Ellish and Taylor Swift.

Beyond that, flannel-loving 90s kids get their fix thanks to Eddie Vedder, Green Day frontman Billie Joe Armstrong and Alanis Morissette. Even classical music fans get a treat courtesy of Andrea Bocelli and Lang Lang - while those after an even smoother groove can look forward to Alicia Keyes, Usher, and Jennifer Hudson.

And for those who like to max out at PG-13, there's Chris Martin, Michael Buble and The Killers - because nothing screams 'lockdown' like a weekend singalong on Houseparty.

So without further ado - here's how to watch One World: Together at Home in the UK, US and more - stream or re-watch the biggest concert of modern times for free no matter where you are in the world this weekend.
