Sandi is also enjoying her ongoing romance with blues rocker Joe Bonamassa, despite missing out on a Christmas vacation in the States due to a bout of swine flu which saw her admitted to Skegness District & General.
She said: "In the middle of the last night of a tour, my keyboard player took me to hospital. I was told I had swine flu. They had all the windows open and wouldn't let me cover myself up because they wanted to get my temperature down.
"When it finally came down they discharged me. I couldn't move from the hotel room for six days until I caught a cab to Newcastle and only then because the cabbie made a bed in the back of the cab. My mum was there to meet me.
"I was on my back for so long. I haven't sang since then because I had such a horrendous cough. I had nausea and a really high temperature. I am still teetering on the edge.
"Flu can do horrible things to someone's voice. It's brutal, so I went to see a voice specialist because I was scared I had damaged my vocal chords.
"Now I am on a health kick and taking 20 vitamins a day and no booze. The worst part was that I was supposed to go to Florida to meet Joe and his parents because he was out there finishing his tour but I never made it.
"I've had common colds and viral stuff but I have never understood the true definition of flu until now. It was horrible. I have never been that ill in my life. It almost killed me."
The couple have since reunited. Sandi said: "I flew to the US last month and met his mother for the first time. His parents are great. His dad is good fun and his mum is the sweetest soul on earth.
"Joe also came to Scotland at Hogmanay. He slept the whole time. I had to wake him up for the bells.
"We had our one year anniversary the other week. We went back to the same place we first met. He and I are really similar people in so many ways. It wouldn't work if one of us was a real rock star. He just puts on his jeans and t-shirt and baseball cap. He's not living the rock lifestyle and neither do I. He is a great performer, a great musician and very sweet person.
"He has adopted the Scottish culture. I got him a kilt for Christmas and a good-looking sporran. He was chuffed.
"But he is exactly like my father, which is scary. We love music, we love guitars, we like cars and we like wine. We are impulsive and little bit scatty. We work well together."
