Members of The Cranberries, Fergal Lawler (C), Noel Hogan (2nd L) and Mike Hogan (R) help carry Dolores O'Riordan's coffin from St. Joseph's church on January 21, 2018 in Limerick, Ireland.
The mother-of-three had been in London to record a cover of Zombie with hard rock band Bad Wolves when she died.
The singer was found on 15 January "submerged face up in the bath dressed in her pyjamas" in her hotel room.
It's a horribly tragic end to what had been a truly iconic career for O'Riordan; as the lead singer of The Cranberries, she and the group enjoyed massive worldwide success in the 1990s with hit songs like Dream, Linger, and Zombie. "Today we continue to come to terms with what happened".
In a statement following her death, her publicist said: "The lead singer with the Irish band The Cranberries was in London for a short recording session".
According to the toxicology report, Dolores" blood had "therapeutic' levels of medication, but it seems that her alcohol level was extremely high: four times over the legal limit of driving.

"There was no evidence that this [was] anything other than an accident".
Coroner Dr Shirley Radcliffe asked Police Constable Natalie Smart if there was any evidence of a note in the room where O'Riordan was found.
Our continued thoughts are with Dolores' loved ones.
It continued: "We'd like to say thank you to all of our fans for the outpouring of messages and their continued support during this very hard time".
Irish Prime Minister Leo Varadkar was among the first to pay tributes, calling O'Riordan "the voice of a generation".
Their second album, No Need To Argue, from 1994, went seven times platinum in the US.
But they canceled many dates on their 2017 Europe and North America tour, with the band citing O'Riordan's ongoing back problems as the cause.
