The A5 , Am(7M) and A5 is basically a step down of the fourth string:
A5 Am(7M) A5
e | ----0-------0--------0------- |
B | ----1-------1--------1------- |
G | ----2-------1--------0------- |
D | ----2-------2--------2------- |
A | ----0-------0--------0------- |
E | ----x-------x--------x------- |
The B7 can be played in various ways, I like the sound of this one:
e | ----2--- |
B | ----0--- |
G | ----2--- |
D | ----1--- |
A | ----2--- |
E | ----x--- |
A5 Am(7M) A5 D5
A gentle breeze from hushabye mountain
F5 A5 B5 E5
Softly blows o'er lullaby bay
A5 Am(7M) A5 D5
It fills the sails of boats that are waiting
F5 A5 E5 A5
Waiting to sail your worries away
D5 B5 E5
A5 Am(7M) A5 D5
It isn?t far to hushabye mountain
F5 A5 B5 E5
And your boat waits down by the quay
A5 Am(7M) A5 D5
The winds of night so softly are sighing
F5 A5 E5 A5
Soon they will fly your troubles to sea
D5 A5 F5 G5
So close your eyes on hushabye mountain
Bb5 D5 B5 E5
Wave goodbye to cares of the day
A5 Am(7M) A5 D5
And Watch your boat from hushabye mountain
F5 A5 E5 A5
Sail far away from lullaby bay
