Randy is playing a black Hagstrom here. A switch from his usual Rickenbacker 4001, which was his go-to bass on the 1977 Hotel California tour. See more of Randy’s basses here.
According to the following review, the band was an hour late for the concert because their contract had the wrong start time:
“Eagles opened the late afternoon concert after an hour of waiting by the audience. The lead guitarist apologized for the delay saying they had been eating barbecued chicken in Birmingham at 3:30 p.m. when they noticed a poster for the concert that said 4 p.m. Their contract said 5 p.m. Panic ensued and the band hot-rodded it to Tuscaloosa.”
