From the dictionary:
Frontman:
1. A person who leads or represents a group, in particular.
2. The leader of a group of musicians, esp. the lead singer of a pop/rock group.
Bruce Springsteen doesn't "lead" the E Street Band--they back him. Tom Petty doesn't "lead" the Heartbreakers--they back him. Prince doesn't "lead" his group of backing musicians--they back him. They're known as backing bands....and Springsteen, Petty, Prince and a slew of other artists are recognized as SOLO artists. How anyone can recognize a solo artist as a "frontman" is beyond ridiculous. They're not.
As for eyes on the "Boon's bulge".....maybe yours are, Dreamboat.
Everyone else is focused in on the whole show and the actual music.
Young man, in the context of a live experience, most people would agree the frontman is the focus of attention. Doesn't matter if the front man is fronting a bunch of hired musicians or a well stablished band. A frontman is someone who fronts something - it doesn't matter what he's fronting - he's still a frontman.
For example Oasis are a well stablished band but no one gives a toss who the other musicians are - all eyes are focused on Liam Gallagher and the non existent bulge in his trousers.
Chris Martin is a frontman for Coldplay (and a better one than Boon) - one could argue the rest of his band are a bit anonymous too.
Your argument as usual is pointless and badly researched. As for your dictionary definition, let's see...
1. A person who leads or represents a group, in particular.
The word 'group' refers to any group of people. Could be a political party, a backing band, anything.
2. The leader of a group of musicians, esp. the lead singer of a pop/rock group.
I think it would be fair to say Leonard Cohen or the Boss lead a group of musicians. Equally Bowie led a group of musicians when he played live. The context those musicians take is irrelevant.
