This 1976 show commemorates the US Bicentennial. Part II, which is a continuation, is generally not followed up. Apparently it didn't make the cut according to OETV.
There are two medleys which each take up over 3 minutes each: Stephen Foster and Cohan. "Dixie" and "St. Louis Blues" also run over 3 minutes. These are balanced out by a 1 minute+ dance number by Bobby and Cissy and Anancani's song. All in all, 15 pieces averaging 2 minutes 24 seconds. Typically for a Welk show.
Probably one of the best theme shows of the run, despite the abbreviated songs. Dale does "Shenandoah" for the umpteenth time. There's "Stars and Stripes Forever," and "The Battle Hymn of the Republic" to round it out.
The 2012 wrap around features Bobby, who has little to say.
