When the group is introduced at their concert, Danny is at Shirley's left with an acoustic guitar, but when the song ("Breaking Up is Hard To Do") begins, Danny is on her right playing a six-string electric.
During the group's introduction at the start of the show, in a distance shot you can see the group playing a song, but you hear no music or singing, just the applause.
When the race starts, the #7 horse (Danny's) has a rider with a blue shirt. A moment later, the #7 horse has a light cream colored shirt. It remains the rest of the race.
