Thinking again U2 were 5 albums & 2 videos in by 85. They had built up a big live following in both the UK & US. Only thing missing was hits in America.
T4F were considered a bit of a pop band. Although not good looking enough to have teenage girls screaming.
They would have been closer pre Live Aid. T4F really needed to release a great album pre JT. But as with a lot bands that suddenly become big, they took a long time.
