It would seem that way according to Lotsawa House, Pero...

The error is consistent, so if the organizers were going for a theme (the Dzogchen teachings of Longchenpa), it makes a certain amount of sense that the prayer is wrongly attributed to Longchen Rabjampa and the empowerment erroneously ascribed to his Dzogchen cycle, the Nyingthik Yabzhi. The prayer is Jigme Lingpa's, and the empowerment belongs to his cycle, the Longchen Nyingthik.
That is, unless someone has evidence to the contrary... We all know that the catchy and meaningful titles of certain texts can be used contemporaneously or recycled over and over again, to the point that they basically become genres (
Calling the Lama from Afar, anyone?)
There are several reasons Garchen Rinpoche would be teaching on such a theme, not just that the Longchen Nyingthik is a popular Dzogchen cycle. It may interest you to know that the connections between Jigme Lingpa and the Drikung lineage are very strong. Drikung_Dzogchen mentions that one of JL's main practices was a terma revealed by Gyalwang Rinchen Phuntsok (the 17th Drikung throneholder), and Malcolm confirms that he indeed received the Yangzab as well (see:

JL was also a close friend of the 3rd Drikung Chungtsang Rinpoche, to the point that JL's only son, Nyinche Özer, was recognized as his subsequent incarnation. This was brought to my attention by orgyen jigmed (see:
viewtopic.php?f=50&t=3291&p=35949&hilit ... ung#p35944) and can be confirmed by the following page on Treasury of Lives:

Incidentally, has anyone alerted the organizers by emailing

"The Sutras, Tantras, and Philosophical Scriptures are great in number. However life is short, and intelligence is limited, so it's hard to cover them completely. You may know a lot, but if you don't put it into practice, it's like dying of thirst on the shore of a great lake. Likewise, a common corpse is found in the bed of a great scholar." ~ Karma Chagme
