Like her son, Jer Bulsara “always had a strong twinkle in the eye”.
May announced on Facebook that Bulsara had passed away last Sunday, quietly and peacefully in her sleep.
Freddie Mercury's mother, Jer Bulsara, has died aged 94
Paying tribute, May wrote: “Jer was a warm and devoted Mum to Freddie, and, like Freddie, always had a strong twinkle in the eye.
“She had an independent spirit and a strong sense of humour. Of course I knew her for over 50 years, and when I first used to go around to Freddie’s parents’ house in Feltham, only a few yards from where I lived, in our student days, Jer was a busy Mum, full of life and optimism.”
“Jer was always a keen follower of our progress as a band, and always came to see us when we played nearby, always with huge enthusiasm,” he continued.
“Freddie was very close to his Mum, and, I think, took a mischievous pleasure in trying to shock her.
“Roger and I remember one night before a show in London (Wembley Arena, I think) when Freddie announced .. 'Mother’s in the audience tonight. Better throw in a few extra ‘f**ks !’”.
May added that after Mercury’s untimely death in 1994, Bulsara stayed close with her son’s bandmates and they consulted with her on project’s remembering the frontman.
“In private moments with us, away from the glare of the spotlights, in latter years Jer was always ready with a cup of tea when we visited,” he added.
“And we were always able to speak about ‘My Freddie' without shyness, feeling that he was not far away.”
