I'm constantly amazed to remember performing certain cover songs with Broken Promise -- sometimes performing them for years -- and going to look at the lyrics, only to confirm that I never once even tried to learn the lyrics. I just sang the first line, sang whatever doggerel over the chords that I wanted, then yelled out the hook line in the chorus.
And all this before I started drinking.
Problem Child by, I think, AC/DC
Problems by the Sex Pistols
Sick as a Dog by Aerosmith
My Fist, Your Face by Aerosmith
Love Lies Bleeding by Elton John
Dr. Love by Kiss
I sense a thread in those songs, but Jesus, I must have performed Problems at fifteen gigs, and surely did the Aerosmith songs more than that.
Yes, even a pickup band could play twenty times year back then . . . .
