Fear and Loathing in Las Vegas

I realize this isn't the Movie section but I feel this movie doesn't fit in any of the categories and to add the whole movie itself is psychedelic.

The purpose of this thread for me anyhoo is to figure out a little secret I'm just wondering about. In the seen when the Flea licks the LSD off Hunter's red woolen shirt, isn't that the bassist, thus Jack Cassady. Just a question off head. Feel free to post any other comments or questions on F&L regardless..
