This tab is better, for I have seen Frampton live. This is how the intro goes:
e|--------------------------------------------------------------------------|
B|-1---3-1------------------------------------------------------------------|
G|---2-----2-0----0---2-0--------0---2-0------------------------------------|
D|------------------2-----2-0------2-----2-0----2-0---0---------------------|
A|--------------------------------------------------2-----------------------|
E|--------------------------------------------------------------------------|
Slowly
Repeat as necessary.
