I can second the good tip on Ken Perlman's book. Taught me everything I know.Another suggestion: Use TablEdit to convert ABC notation from Henrik Norbeck's collection of Irish session tunes to 5-string tab. It will take a fair amount of work to polish the conversion results into usable tab, but that will shorten the tune learning by the same amount, so you break even. Then when you have a usable tab file, email it to me. Thanks, I appreciate that.
You can also try this URL: www.sessioneer.com but I haven't been able to get it to work (server too busy error) as I was posting this.
