Can anybody give me some advice as to their recommendations as to what is good to see in Buenos Aires and also which tango shows to see.

Barry,

You might try this Blog: http://landingpadba.com/
and check out earlier posts on this Forum and TA Buenos Aires.

So many good suggestions for Tango shows. My favorites, so far, are La Ventana, and for a smaller venue in a fabulous cafe (not the food) upstairs at the Cafe Tortoni.

A good Guide Book - Fodors Buenos Aires (or Argentina) and others would help you get an overview and pick and choose from your own interests.

Have a good visit.

What made you want to visit Buenos Aires, barry?
I will add Rough Guides to your reading list.
I would recommend you read everything you can on Buenos Aires and see what there is that appeals to you and then you might have more specific questions ..
Look at the neighborhoods, the amazing parks, the sightseeing... listen to the music , read about the over 100 museums in the city ....
Have a good time researching

thanks

Here is a link to a post which asked a similar question a while ago which should provide a few ideas:

Like marnieWDC we enjoyed Cafe Tortoni and were lucky enough to get a table right by the stage. A few photos -

I went to Cafe Tortoni as well and it was a good show, but only one couple, so it depends how much tango you want to see. Tortoni was a good introduction. You can also see free tango on the streets in La Boca.
