 Cyrus performed " I Miss You " as an encore on sporadic dates of her first headlining tour , the Best of Both Worlds Tour , which extended from October 2007 to January 2008 . The tour 's concert film uses the performance within the set , although it was not performed as such . The performance had Cyrus dressed in a white tank top , blue cardigan , and denim pants , and sole on the stage . She sat on a stool that placed towards the end of the runaway , performing with an acoustic guitar , as images and home footage of Ron Cyrus appeared on the screens . Chris William of Entertainment Weekly attended the November 8 , 2007 concert at the San Diego Sports Arena in San Diego , California , and wrote , " So it was especially sweet when , for the encore , she ditched the dancers and enhancers and strummed an acoustic guitar on ' I Miss You , ' vulnerably serenading her late grandpappy — and , for once , really looking and sounding 14 . Not everyone noticed because , when she finished , half the seats were empty . " Alison Bonaguro Dressed of the Chicago Tribune stated that , despite its simplicity , the performance on December 8 , 2007 at the Allstate Arena in Rosemont , Illinois felt like as though it was the largest production of all . In a gray shirt and black pants , Cyrus performed the song , along with " Ready , Set , Don 't Go " and " The Best of Both Worlds " , on The Oprah Winfrey Show on December 20 , 2007 , as a screen displayed a light @-@ blue background . On October 5 , 2013 , as part of a Saturday Night Live skit , Cyrus performed an excerpt from " I Miss You " with actress Vanessa Bayer .
