It was an amazing moment for Taylor Swift fans in Nashville this weekend.

Swift was joined on stage by rock icon Mick Jagger of The Rolling Stones for a rendition of their hit “Satisfaction.”

It was the highlight of the night for many in the audience, but one fan’s reaction was priceless. A 72-year-old grandmother had no idea Jagger would be on stage when she bought her tickets, so she could take her granddaughter.

The best part is the grandmother missed a Stones concert earlier this year because of some health problems.

“My mom has had a lifelong dream of going to a Stones concert, but due to a serious health issue this past year she missed their tour. It was upsetting to her and a big disappointment,” the woman’s daughter posted on YouTube, where the video has been viewed more than 85,000 times.

She went on to thank the people who have shared the video – including Taylor Swift: “Needless to say there has been a lot of tears and laughter, it has been a memory of a lifetime. We are honored Taylor even watched it. We are so blessed to just have my mom healthy and on her feet, let alone acting like a teenage groupie!”
