We had to learn lots of things for recitation — biblical passages (we're talkin' back in the dark ages when they still had Bible classes in public schools), poetry, Shakespeare, the above-mentioned run of rah-rah Americana.Never a problem for me unless I stopped and though about what came next. I've always been able to just let my mind relax and memorized words just pour out.
Can't say I remember many of those things now, but I think that may be because it's been more than 40 years since I've had to and in the interim I've jammed in litearlly hundreds of songs I can sing without a hitch.
Hadn't really thought about incorporating recitation into performances, but it might be fun to give it a try.
