This recording includes everything the first tenors are likely to sing, which means that in the act 2 finale they are both 'seguaci del conte' and 'seguaci di Manrico'. As both factions have the same music (with different words) most of the time this isn't a problem except for two bars about halfway between figures 50 and 51, where I have simply played both parts in sequence.
First tenors split in the fourth act: there is a separate file for each.
