Sliding into chords-20's banjo style

Been a while since I've posted here. I've been busy wailin' away on the uke.
I would love to learn to slide into chords the way Ukulele Ike did using the old time plectrum banjo style of the early 20th Century. Any good video instructionals out there?

*bump* 'cos I wanna know, too!

Hey both of you were hiding or what.....welcome back and happy Strummings...MM Stan
