The guitar in the next bit is barely audible. I spent a long time trying to figure it  
but I ended up writing this (goes with the singing, but i'm not exactly sure it's what he plays): 

|------|-----|------|------| 
|------|-----|------|------| 
|------|-----|--10--|------|     The strumming pattern is pretty straight 
|--10--|--8--|--8---|--10--|     forward. I'm sure you can manage. 
|--8---|--6--|------|--8---| 
|------|-----|------|------| 

"You don't have to worry" (again, no strumming): 

|------|-----|------|------| 
|------|-----|------|------| 
|------|--8--|------|--10--| 
|--10--|--6--|--10--|--8---| 
|--8---|-----|--8---|------| 
|------|-----|------|------| 

You can hear towards the end he slips in:
