Before going in for her last round of chemotherapy, Ann Trachtenberg jokingly said she wanted a band to escort her after the treatment was done.
Her niece decided to follow through with her wish and surprised her in the best way possible.
She contacted the University of Wisconsin Marching Band and to her surprise, they accepted her request to play for her aunt.
The band's performance was recorded and the video has gone viral.
Trachtenberg is very emotional when she sees the band, and is even seen hugging one of the band members.
