Tom Waits fans accuse Adele of copying his 1973 track Martha

The vocal powerhouse released her comeback track Hello last month and some think it bears similarities to Martha

Some reckon the two songs sounds similar

Fans of American singer Tom Waits have accused Adele of copying one of his famous tracks.

Some have said the British singer's latest record-breaking song Hello bears similarities to Martha, a song the American star penned in 1973 and appeared on his album Closing Time.

On it the 65-year-old sings about calling a former flame who he then pours his heart out to despite being married.

It begins: "Operator, number please, it's been so many years, will she remember my old voice while I fight the tears?"

Taking to Twitter after hearing the London-born star's song, one shared: "Adele's Hello is pretty much another version of Tom Waits' Martha."

While another wrote: "Adele I love you BUT Tom Waits nailed that song on his 73 debut."

And: "Sorry but I'm going to have to be Scrooge at this 'Wow isn't Adele clever' party. Tom Waits did it better.

Producer and songwriter Greg Kurstin, who worked with Adele on the huge comeback single, recently said that she wanted to make something "real and believable" like Tom Waits.

He told Entertainment Weekly: "She didn't want to just go through and write a pop song with any particular formula. We talked about Tom Waits and different storytellers like that.

"I think that was the idea, that we wanted to do something that was very honest about where she was at right now, and she wanted to do somethign that was real and believable. "

He went on to say they wrote Hello from "nothing", revealing that it was just "something we stumbled on when we were playing in the room."
