This is an arrangement of the song Life Could Be A Dream by the Chords, who were a popular group in then 1970s. I also have a Low Reeds version of the same song. No, I do not know why the alto stops in the middle of the solo or why the bari rushes. All I can say is to stop it and start it again where you left off. Send me a video of your group playing this at 7thOneManBand@gmail.com.
