John Lennon

The Liverpool band could have their first chart-topper in 54 years

Now And Then, written and sung by Lennon is the last song to ever be credited to him, Sir Paul McCartney, George Harrison and Sir Ringo Starr altogether.

The track, sourced from the demo, used technology to extricate and isolate Lennon's voice and was recorded by the singer in the late 1970s.
