Back up... there were scenes of Susan and Dan Stewart in the 70s on Youtube a few years ago?
I would love to see some footage of Susan in the 70s. Much as I love the string of 79/80 episodes that are available, I hate that they take place just after Dan has passed and Susan has left Oakdale.
Not quite so classic, but still a very memorable moment - Tracy's return in 2003. It won't embed, so here.
I will never forget this, as my exposure to Tracy had been minimal before the 21st century. I started watching in '93 right around the time she left, and I only had very vague memories of her from '96 and on The City as I was in school and could only fake sick so much. Tracy's reputation preceded her, but seeing her in the flesh Jane Elliot was an incredible shock of adrenaline to the show and the cast in a particularly moribund, Fab 4-obsessed period that year. She upended every scene she entered.
IIRC her first return was a brief stint to bring on Scott Clifton's Dillon and de-Q Skye - a vindictive stiletto in the ribs from Guza to JFP's reign, which as an OLTL fan I deeply enjoyed; I hated Skye acting like she belonged there - but JE was so, so good that I thought they'd be insane to keep her gone for very long. And they didn't; she was back on contract within months.
I remember her hysterically dissing each of the Qs in turn. Stuart Damon's reaction to Tracy cutting Alan down to size does not appear to be acting - he looks delighted.
