We had security guards keeping us from the washrooms and duty free
And once past the check point, we couldn’t get back to our gate again.

Heathrow early morning
The flight over was uneventful, but long. At Heathrow, we went

through tunnels with all our baggage. Off to Shannon and the Emerald Isle.
