Babasónicos and Juana La Loca were the support acts.
Here is Daryl Bamonte's entry for the famous Devotional Tour Diary, published in Bong magazine in 1994:
I think we’re witnessing “Beatlemania” down here. These people are crazy about DM and crazy in general. They are all such nice people though. “Kill an Argie, win a Metro” seems like a lifetime away now… Somebody decided to mention something in passing today. There’s going to be 40,000 in there tonight. Thanks for dropping that into the conversation…
