Touring versions from Foggy G's We're Only In It For The Touring:

1974
Probably the most performed song of the Fall '74 tour, as it was used to open and usually close almost every show (except for a handful of shows at the beginning of the tour). The tune was performed differently each night, and was sort of a Nightly Update on the band's happenings. While the musical structure of the tune was essentially the same nightly (although it would vary in length), the vocal content was different. Duke and Brock would comment on whatever strange things were happening with the band, poke fun at Ruth and Chester, and update us on the continuing saga of Marty Perellis. In my opinion, always funny and a great way to start each show.
1975
By this tour, this song had pretty much developed into what would eventually appear 5 years later on "Joe's Garage". The tune starts as on "Joe's Garage", with the horns being a nice addition to the musical landscape. Brock sings the first two verses and choruses, then we get an instrumental verse and chorus with a short FZ solo concluding the affair. Unlike on the previous tour, Brock is not free to simply improvise the lyrics, but is singing a predetermined set of words.

Scott Thunes says:

I am positive that tengo (which did NOT have a name when we performed it) was not a studio track so I'm going to go out on a limb here and say that it must have been another sound-check track. The vocals most likely were from the same soundcheck. Massimo probably lipsynched to the track in the studio [for the video]. I'll have to rent it now! As a matter of fact, I'll lay money on it. Soundcheck track. Boom. Done.

Mike Keneally (1988 Was A Million Years Ago)

[Boston, February 19, 1988] At rehearsal we performed "Tengo Na Minchia Tanta", "T'Mershi Duween", "Why Don'tcha Do Me Right", "Brown Moses", "Sinister Footwear", "Sy Borg" and "Token Of My Extreme". "Sy Borg" was one we had never played before, and fortunately I knew the chords, so we were able to do a reasonable version of it and give Frank the overriding feeling that it was a doable song, which is good because it's a very nice song.
