Now pointless fillers

The thing that struck me about the rediscovered Morecambe & Wise episode from 1971 was the musical numbers, which were shoved in as breaks as part of a formula.
    I knew who Kenny Ball was but the lady doing the operatic version of a Beatles (?) dirge – I kept waiting for Eric to charge in to do a wind-up.
    And the bloke doing My Way – I had no idea he was the bloke wot wrote it.
