Seed....And they call it fun? sounds like a punishment to me.
I thought I wanted RUS before I saw one at a bookstore a few years ago. The brevity of its entries is the worst drawback. I'm a collector from the opposite end of the spectrum, wanting to find the entire 'original', including (especially) the obscure verses. Then I can decide what I want to sing.
For example, how can you have any fun with "The Man on the Flying Trapeze" if there's no one there who knows the whole thing? But that would probably get me blackballed from an RUS group.
Just my $0.02.............Tiger
