The loved-up couple took the tube to Rod's big performance at London's O2 Arena.
Queen has released ‘Let Me In Your Heart Again’, with vocals from the late Freddie Mercury.
The song has been remixed by William Orbit for this release using Mercury's original vocals.
Queen's Brian May released a statement on the cause, which said; "It's been 23 years since the world lost our beloved Freddie Mercury. We've made extraordinary progress in the fight against AIDS in that time. But we cannot simply rest on the fact that the treatment is available. We must ensure that it is provided. Roger and I are proud to lend this rediscovered song to the (Coca-Cola) RED campaign, in the hope that Freddie's powerful voice can inspire the world yet again."
