newbie: bar lines and lead ins

[Joe Mc Cool]

Please,

\time 6/8 \key g \major g'8                                           \bar "| "
\repeat volta 2 {
   b'8 ^"G" a'8g'8b'8 a'8g'8                                          %\bar "|"
   b'8 ^"Bm" a'8b'8b'8c''8d''8                                        %\bar "|"
   b'8 ^"G" a'8g'8b'8a'8g'8                                           %\bar "|"
   a'8 ^"D" b'8a'8fis'8e'8d'8                                         %\bar "|"
   b'8 ^"G" a'8 g'8b'8a'8g'8                                          %\bar "|"
   b'8 ^"Bm" a'8b'8b'8c''8 d''8                                       %\bar "|"
   e''8 ^"C" g''8e''8d''8 ^"G" c''8b'8                                %\bar "|"
   a'8 ^"D" fis'8a'8g'4 ^"G"                                          %\bar "|"
}

I would like this to print as: 

g|bag bag|bab bcd| ......

but Lily shows it with the first bar line missing and remainder in the
wrong places.

I know I can put the bar lines in manually, but that is a pain. 

In essence I need "print one or two lead-in notes, a bar line and then
start counting".

My searches of the LM have failed to find this.
