I also have found my students to have been "to involved" with tag questions.
The last time I did tags, I gave them a cloze using the poem/song "Alexander Beetle". After filling in the blanks, they could read each line and supply the tags.
The only problem was they were so busy listening to this song that they had never heard before, they had to do the listening several times. By then, some of them were singing and laughing as well.
These were Senior grade 1 students in China, aged about 14-16.
